Andy Murray emotionally opened up after his first-round French Open defeat to Stan Wawrinka and admitted that his body struggles to cope with elite tennis.

Murray lost in straight sets and waved goodbye to the Paris supporters as he exited the court, having previously hinted at retirement later this year.

“Yeah, physically tennis is not easy for me nowadays,” Murray said in his post-match press conference. “It’s hard, and, you know, clay has always been a surface that since the very beginning of my career I’ve had back issues on, you know, on the clay, and it’s something I’m sort of used to, to be honest.

“Yeah, it had been a bit of a struggle to sort of in the training and in the buildup, but I felt pretty good going into the match tonight, considering. And yeah, it wasn’t much of a factor out there this evening, to be honest.

“Hopefully I’ll be fine for the doubles. I don’t know when we’re scheduled to play but I imagine it would be a bit later in the week with the other guys, with Dan (Evans) and the opponents, I think they’re both playing tomorrow, one of them pretty late. Yeah, hopefully will be all right.”
