Great Britain continue their defence of the Davis Cup against Japan with a potentially pivotal doubles match at the Barclaycard Arena in Birmingham. The tie stands at 1-1 after Andy Murray and Kei Nishikori won their singles matches.

With the outcome of the tie still in the balance, there has been much speculation surrounding the makeup of the two doubles teams. The most probable scenario is that both sides play their strongest players, Murray and Nishikori, even though they could each line up with a more consistent doubles team, too.
Murray's potential inclusion alongside his brother Jamie would be at the expense of Dominic Inglot. But Britain's Davis Cup captain Leon Smith has no worries about omitting any of his players, insisting it is just the nature of team sport.
"If that happens again, then that is team sport. He's really used to that too, because he knows the college system. I never have a problem with Dominic - the most important thing is to have an open dialogue during the week. That's one of the first things we talk about when we get together. We just talk bout it - it's not behind-closed-doors conversations. It's not cloak and dagger.
"It's out there, everyone knows. We've got Andy, who is one of the best players on the planet, and Jamie who is number two in the doubles, you kind of know where you're at," he told a pre-match press conference.
Andy has barely played since the Australian Open in January, following the birth of his baby daughter, and Smith has full confidence in whoever takes the court for Great Britain. "Hopefully Andy feels good but honestly, even if he does not want to play, we've got another very good guy in Dominic ready to go as well," he said.
"I'm quite relaxed. But that is our strongest team, Andy and Jamie, so we hope he can play."
