Greg Rusedski believes Andy Murray is incapable of winning a Grand Slam again, saying it's physically 'beyond him' now.
Murray is trying to fight his way back from the hip injury that nearly ended his career three years ago, and he looked to be struggling in recent months.
He has vowed to carry on, despite having to play with a metal hip, but Rusedski says he must do so with realistic expectations.
"Yeah, I don’t think he can win majors physically. Mentally, tennis-wise, yes," Rusedski told Metro. "But physically it’s getting harder.
"Not only do you have Djokovic and Nadal, you have [Dominic] Thiem, [Daniil] Medvedev, [Stefanos] Tsitsipas, [Alexander] Zverev, [Andrey] Rublev – who has had an unbelievable season, and not only do you have to beat those guys back-to-back but you have to beat three or four guys from the draw to win a major.
"So can he have a run where he reaches the second week of a major? Possibly. Can he win one? I think that’s beyond him.
"Just because of the physical capabilities to win a three out of five-set major. But you’ve got to give him credit for an amazing career and everything he’s done."
While Rusedski doesn't believe Murray can win a Slam again, he does think he can be a nightmare draw for one of the top players and capable of causing a major upset.
"Djokovic and Nadal are healthy, Thiem has won a Slam. Can he have a magic moment where he beats these guys at a Slam? Yeah, he can beat them.
"But can he win seven matches in a row? That is the problem.
"The later you’re going in a Slam, the guys aren’t playing worse, they’re playing better with every match. So you have to lift your level every match.
"That is the problem unfortunately. I’d like to see him win another Slam but realistically I don’t think it’s possible."
