British captain Leon Smith says whether or not to recall Andy Murray for Friday’s quarter-final against Germany at the inaugural Davis Cup finals is one of his “more difficult decisions”.

Murray, 32, was rested for the Group E victory over Kazakhstan which booked their last-eight spot in Madrid.

With Britain facing the Germans at 16:30 GMT, Smith says he will make his decision in the morning.

“Andy is a team player and understands what is best for the team,” he said.

Former world number one Murray looked sluggish as he laboured to a three-set win over Dutch world number 179 Tallon Griekspoor in the opening group match on Wednesday, admitting afterwards he was still “a couple of kilos” heavier than he would have liked after gaining weight while taking time off with his new-born son and family.

In the Scot’s absence, Kyle Edmund played one of his finest matches of the year to beat Kazakhstan’s Mikhail Kukushkin before Dan Evans was overpowered by Alexander Bublik in three sets.

British number one Evans, 29, is yet to win in the Madrid finals, although Smith is backing the 29-year-old to “find a way” to win.

Following 24-year-old Edmund’s performance, it appears likely Evans will make way for Murray’s return – if Smith decides he is in good enough shape.

“There is no awkwardness about who is going to play, who isn’t going to play, it is a good, open and honest discussion. That’s what we will do again,” Smith said.

“It might be one of the more difficult decisions I’ve had to make, but it is also better when you have got the quality we’ve got to be able to have those discussions.

“We can look at who is in the best physical condition, and look at the match-ups again, linking those factors together to do what is best for the team.

“Because we are scheduled tomorrow evening it gives us time to see if everybody is right and how they feel.”

Germany reached the quarter-finals by topping Group C, winning five of their six rubbers against Argentina and Chile.

Philipp Kohlschreiber, their experienced second-ranked singles players, has dropped one set in his two victories, while leading player Jan-Lennard Struff is ranked higher than any of the British players at 35th in the world.

Struff dropped their only rubber in a three-set loss to Chile’s Cristian Garin on Thursday with French Open champions Kevin Krawietz and Andreas Mies showing their class by cruising through the doubles matches.

“I think it will close, a 50-50 match again, although we shouldn’t have anything to fear,” Smith added.

Who else is in the quarter-finals?

Barcelona footballer Gerard Pique has overseen the transformation of the 119-year-old competition into a season-ending ‘World Cup of Tennis’, which saw the 18 nations split into six groups of three.

The six group winners automatically qualified for the last eight with the two best-placed runners-up joining them.

The quarter-final line-up is:

• Australia v Canada
• Serbia v Russia
• Great Britain v Germany
• Argentina v Spain

Australia take on Canada later on Thursday in the first last-eight tie, with the other three matches taking place on Friday.

Serbia face Russia from 09:30 GMT while Friday’s other two ties are both due to start at 16:30.

Scheduled start times of both sessions have been moved forward 30 minutes after late finishes earlier this week, with a tie between Italy and USA concluding at 4:04am local time on Thursday. In addition, the break between the first and second singles rubbers has been cut from 20 minutes to 10.

The same start times will be in place for Saturday’s semi-finals.

Novak Djokovic ensured Serbia moved into the Davis Cup quarter-finals as Group A winners with a straight-set victory over France’s Benoit Paire.

The world number two won 6-3 6-3 after team-mate Filip Krajinovic overcame Jo-Wilfried Tsonga 7-5 7-6 (7-5) earlier.

Germany beat Chile 2-1 to win Group C and set up a last-eight tie with Great Britain on Friday.

Australia face Canada in the first of the quarter-finals from 17:00 GMT on Thursday.

The other three ties are on Friday with Serbia taking on Russia from 09:30.

Great Britain face Germany and Spain play Argentina from 16:30.

Scheduled start times of both sessions have been moved forward 30 minutes after late finishes earlier this week, with a tie between Italy and USA concluding at 4:04am local time on Thursday.

• GB beat Kazakhstan to reach Davis Cup quarter-finals

Kyle Edmund stepped up in Andy Murray’s absence to give Great Britain the perfect start against Kazakhstan in a decisive Davis Cup group tie in Madrid.

Assured of a quarter-final place with a victory, Britain lead 1-0 in the three-rubber tie after Edmund won 6-3 6-3 against Mikhail Kukushkin.

British number one Dan Evans will put his team in the last eight if he beats Alexander Bublik later on Thursday.

Murray has been rested as he continues his comeback from hip surgery.

If Evans loses, Britain will have another chance to win the tie through Jamie Murray and Neal Skupski in a deciding doubles rubber which follows the second singles match.

Kazakhstan, backed by a rowdy set of supporters, need to fight back to win or they will be eliminated from the new-look 18-team finals tournament which is being played across the week in the Spanish capital.

Britain could still reach the last eight as one of the two best runners-up even if they are beaten by the Kazakhs, although it would only be a slim chance with Group B runners-up Russia already guaranteed to qualify ahead of them.

Edmund rediscovers form to give GB advantage

Murray’s absence was unsurprising after the Scot laboured to a three-set win over Dutch world number 179 Tallon Griekspoor on Wednesday, which left him admitting he was not as sharp as he would like to be after taking a month off competitive tennis to spend with his new-born son and family.

That placed the pressure on 24-year-old Edmund to perform, at the end of a year in which he struggled for wins and tumbled down the world rankings as a result.

But Edmund, the 2018 Australian Open semi-finalist who has dropped to 69th in the world, outplayed 67th-ranked Kukushkin in a noisy Caja Magica.

Kukushkin was backed about 100 boisterous and colourful fans, armed with drums and a trombone like they were when their women’s team played Britain in the Fed Cup earlier this year.

However, that did not put off Edmund, who himself was well supported by a noisy contingent of Union Jack-waving British supporters, who have travelled to Madrid in their droves.

Edmund showed no signs of the troubles which have plagued him on the ATP Tour this year, hitting 10 aces and 23 winners in a dominant performance.

The Yorkshireman’s explosive forehand – his key weapon – was particularly destructive, helping him take his fourth chance in the decisive break of the first set and save two break points in the following game.

After breaking again for a 4-2 lead in the second set, he took eight of the last nine points to race through the closing stages, converting his first match point when Kukushkin hit a forehand long.

That meant Edmund won in just one hour and 15 minutes, leaving the celebrating British fans dancing in the stands, while finally silencing the Kazakhs.

“The atmosphere has been amazing, I think we have got the most travelling fans so amazing to get so many people coming here from Britain,” Edmund said.

“I couldn’t wait to get out here and it was such a buzz to thrive off the crowd.”

How Britain’s qualification hopes could pan out

Barcelona footballer Gerard Pique has overseen the transformation of the 119-year-old competition into a season-ending finals, which sees the 18 nations split into six groups of three.

The six group winners automatically qualify for the quarter-finals with the two best-placed runners-up joining them.

Britain’s 2-1 win over the Netherlands in their opening group match on Wednesday means they will top Group E by beating Kazahkstan.

• If Great Britain win the tie (either 2-1 or 3-0) they qualify for the quarter-finals as group winners
• If Great Britain lose the tie 2-1, they will not qualify as one of the two best runners-up
• If Britain lose 2-1 to the Kazakhs then their hopes of progressing go down to the percentage of matches won
• Following the win over the Netherlands, Britain have 2-1 record, meaning they would finish with a 3-3 (50%) match-win percentage
• That means they can’t overtake Russia, who are currently the leading second-placed team with a 4-2 (67%) match-win percentage
• A 50% match-win percentage for Britain would place them alongside Argentina and Belgium, meaning it would go down to a set-win percentage
• Britain currently have a 7-3 (70%) set record but if, in the best-case scenario, Evans and Murray/Skupski both lost 2-1 that would give them a 9-7 (56.25%) set record
• * Argentina, who are now guaranteed to finish as Group C runners-up after Germany won their opening rubber against Chile, have a 8-6 (57%) set record

Rafael Nadal’s Spain eased into the quarter-finals at the Davis Cup finals, beating a weakened Croatia to send the defending champions out of the event.

With Croatia missing Marin Cilic and Borna Coric, doubles specialist Nikola Mektic had to play singles against Roberto Bautista Agut, losing 6-1 6-3.

Nadal then beat Borna Gojo 6-4 6-3.

Meanwhile, Serbia, who won the Davis Cup in 2010, put themselves in pole position in Group A with a 3-0 victory over Japan at the Madrid event.

Filip Krajinovic defeated Yuichi Sugita 6-2 6-4, Novak Djokovic thrashed Yoshihito Nishioka 6-1 6-2, and Janko Tipsarevic and Viktor Troicki clinched a tight doubles match against Ben McLachlan and Yasutaka Uchiyama, winning 7-6 (7-5) 7-6 (7-4).

Germany also triumphed 3-0 as they defeated Argentina. Philipp Kohlschreiber battled back from a set down to defeat Guido Pella 1-6 6-3 6-4 and Jan-Lennard Struff was too good for Diego Schwartzman with a 6-3 7-6 (10-8) success.

In the doubles, the German pairing of Kevin Krawietz and Andreas Mies overcame Maximo Gonzalez and Leonardo Maye after the longest tie-break in Davis Cup history as they won 6-7 (4-7) 7-6 (7-2) 7-6 (20-18).

Great Britain’s near nine-hour tie with the Netherlands,which ended in a 2-1 victory for GB, meant that the tie between Australia and Belgium to decide who will win Group D started two hours later than scheduled.

Spain’s victory over Russia on Tuesday had finished in the early hours of Wednesday and a similarly late finish looked on the cards for both Australia v Belgium and the Group F match between the United States and Italy as questions over scheduling arose at the re-vamped competition.

The United States were at the centre of controversy after group winners Canada conceded their doubles rubber on Tuesday when they had an unassailable 2-0 lead.

It meant the US were given a 6-0 6-0 win for the doubles, which could potentially help them qualify for the last eight as one of the two best runners-up.

Organisers the ITF said three Canadian players had been declared unfit to play, but Britain’s Andy Murray was among critics of the decision to forfeit, saying: “I don’t think that’s good.

“So where Canada may have felt that that was a dead rubber in theory for them because they were already through, that could have implications to all of the teams potentially that might finish in second place.”

Andy Murray survived a scare against Dutch world number 179 Tallon Griekspoor before giving Great Britain a winning start at the inaugural Davis Cup finals in Madrid.

Murray, 32, lost the opener in the new best-of-three sets format before winning 6-7 (7-9) 6-4 7-6 (7-5).

The group stage tie continues when British number one Dan Evans plays Robin Haase later on Wednesday.

Jamie Murray and Neal Skupski will play in the doubles to round off the opener.

Britain, who won the 2015 Davis Cup in the previous format, have been drawn against the Netherlands and Kazakhstan – who they face on Thursday – in the group stage.

Eighteen nations are contesting a football-style knockout tournament for the first time to determine the Davis Cup champions, with the winners of the six groups and the two best-placed runners-up reaching the quarter-finals.

Brilliant atmosphere & thrilling finale

Barcelona footballer Gerard Pique has overseen the transformation of the 119-year-old competition into the season-ending finals, which has been met with fierce criticism from some and doubts about the atmosphere such a format would create.

While Spain’s opening match on Tuesday night was unsurprisingly watched by a partisan and full crowd at the Caja Magica, some matches have struggled to attend spectators.

Britain’s opening tie against the Dutch was not expected to be one and so it proved as about 1,000 Union Jack-clad fans created a boisterous atmosphere on a 2,500-capacity third show court which was about three-quarters full by most estimates.

The crowd was given plenty of entertainment by Murray and Griekspoor in a gripping match full of ebbs and flows, a final-set tie-break providing a thrilling finale which eventually separated the pair.

Supporters from both nations were left standing on their feet and roaring their player towards victory in the tie-break, with Murray sealing the type of win he has earned throughout his illustrious career after two hours and 51 minutes.

“The atmosphere was one of the things players were worried about in a neutral venue but both sets of fans were fantastic,” Murray said.

The new Davis Cup format

Eighteen nations are split into six groups of three, with the group winners and two best-placed runners-up progressing to the quarter-finals.

The two semi-finals will be played on Saturday, 23 November with the two winners going through to the final on Sunday, 24 November.
