Great Britain captain Leon Smith has revealed that he will make his decision regarding Great Britain's second singles player for next week's Davis Cup final sooner rather than later.

Smith named a five-man squad for the clash against Belgium in Ghent, but he must now select who out of youngster Kyle Edmund and James Ward will play alongside Andy Murray in the singles encounters.

"Ideally I'd like to decide as early as possible so whoever plays gets their head around it and, importantly, we can be very specific in our preparations," he told reporters.

"It definitely dictates how you can train on the Monday, Tuesday, Wednesday, Thursday, because you would mimic the way they're sparring against who we think is the most important match for that number two player.

"Also, of course, to allow some time for what would be major disappointment for the persons that aren't playing, because it's big for them."

Twenty-year-old Edmund won the Buenos Aires Challenger title on Sunday.
