Friendship will be left in the locker room when Andy Murray takes on Thanasi Kokkinakis in the first singles match of Britain’s Davis Cup semi-final against Australia in Glasgow today.

“I expect a tough match,” said the world no.3 three after yesterday’s draw.

“I know Thanasi well. I spend time with him away from the court. He’s a really nice person, very respectful, a hard worker, good manners and all that stuff... I really like him.

“But this weekend we’re obviously rivals, hopefully I’ll be able to use my experience in these situations to my advantage,” added the Scot.

“It can obviously work in a positive way for him that he goes out with no fear but it’s also going to be tough playing in this atmosphere for him. Hopefully I can try and get the first point on the board.”

Britain are trying to reach their first final since 1978 but their no.1 caused fears for his health when he missed an official dinner on Wednesday, saying he felt unwell.

Murray said yesterday he felt good but had needed to rest after tough matches and late finishes at the US Open.

Britain have opted for 25-year-old Dan Evans, ranked 300th in the world, for the second singles slot and he plays 23rd-ranked Bernard Tomic.

US Open doubles runner-up Jamie Murray will team up with Dominic Inglot, who reached the men’s doubles semis in Flushing Meadows, for the third rubber against Samuel Groth and Lleyton Hewitt tomorrow.

Evans was preferred over Kyle Edmund and James Ward for the second singles slot.

The winners of the tie face either Belgium or Argentina in the final from November 27 and 29.
