Andy Murray expects to decide on Monday evening whether or not he will make a final singles appearance at Wimbledon.

The two-time former champion has been in a race against time since struggling with a back problem at Queen’s Club that led to weakness in his right leg, resulting in him undergoing surgery last weekend to remove a spinal cyst.

On Thursday, Murray rated it unlikely that he would be able to play singles, with an appearance in doubles alongside his brother Jamie more probable, but he gave a more upbeat assessment at a press conference on Sunday.

“It’s been obviously a tough 10 days or so since Queen’s,” he said. “Obviously I had the operation on the back, which wasn’t insignificant. I’ve just been trying to do everything that I can to try and get ready to start the tournament here.

“I don’t know if that’s going to be enough. I’ve been practising for the last few days. I played a set today. It went pretty well, but I still don’t have 100 per cent feeling and sensation in my leg yet.

“It’s getting better every single day. Like I said a few days ago, I want to give it every single chance that I can to get there.

“I’m going to play another set again tomorrow. I’m doing some physical testing in the morning to see how far off I am from a physical perspective. Then I will probably make a decision tomorrow evening after that.”
