Novak Djokovic was able to overcome Milos Raonic despite his injury because he is able to 'raise his game' when it matters, says Tim Henman.
There were serious doubts about whether or not Djokovic would even be able to play the match at all after he sustained the injury in the previous round.
However, he made his way onto court and, despite some clear physical discomfort, beat Raonic in four sets to book a quarterfinal spot.
Henman, who covered the match for Eurosport, said it was testament to just how good the world number one is.
"There were question marks before the match about how he was going to be with the injury, and then there were question marks again when it was one set all, would he be able to stay in there and stay resilient," Henman said.
"As is so often the case when he was asked the questions, he raised his game. For me, that third set was going to be critical.
"Once he got that to go two sets to one up you felt like he was in the driving seat. He’ll be very, very pleased to finish that off in four sets.
"When you analyse Djokovic’s performance he’s so consistent, there are very few dips, when it went to one set all he really needed to get back that authority.
"Once the point is neutralised, Novak Djokovic is one of the best from there.
"He must be so satisfied to come through this match, even though he’s already beaten Raonic so many times it’s still a dangerous match against a player with a serve like that so he’ll be delighted."
