Then at the end, yeah, I mean, look, it's obviously amazing to win the match, but I also want to go to bed now. It's great, great. But I want to sleep," he added.

"Yeah, I mean, it was. I mean, by far the longest match that I played. The conditions, that's what's going to happen. You play in cold conditions, at that time of the day, with balls like that, you're going to get long rallies, long points. Yeah, I mean, I actually felt better on the court today physically than I did the other day, which is a positive thing. But, yeah, finishing at 4 isn't ideal," Andy Murray said.
