Mats Wilander believes that Novak Djokovic has a 'legitimate injury' amid accusations of faking, and he has described it as 'a big worry' for the Serbia star.
Djokovic was clearly out of sorts and struggling to move with his usual fluidity in his French Open quarterfinal win over Pablo Carreno Busta on Wednesday.
He twice called for the physio during the changeover only to be later accused by the Spaniard of feigning injury.
Not only does Wilander believe those accusations are unfounded, though, he also thinks the world number one is actually playing the injury down.
"I think Novak’s injury is a big worry," Mats Wilander told Eurosport.
"He obviously doesn’t want to show his opponent that he is injured walking onto the court.
"Pablo Carreno Busta hinted that he always does that – I don’t think Novak wants to do that when he’s down.
"I don’t think he wants to show his opponent that he is feeling an injury.
"It’s a legitimate injury that’s going to be there and if he doesn’t get a good start then that could be a problem.
"Clearly it took him some time to warm his body yesterday, and that’s going to be the same tomorrow and again in the finals.
"I would say it’s a worry for sure because these next two matches for any player are going to be absolutely brutal in length and physicality.
"You are going to run for a long time. They will be two marathon matches."
Novak Djokovic will face Stefanos Tsitsipas in the semis before a likely final against Rafael Nadal if he comes through it.
