Novak Djokovic has been told he must raise his game to avoid being dumped out of Wimbledon.

World No. 1 Jannik Sinner stands in the way of the 38-year-old reaching a remarkable seventh consecutive Wimbledon final.

But former British No. 1 Tim Henman said: “I think Sinner goes into that match as the favourite.

“There were concerns over Sinner’s elbow, but he was able to raise his level. He’s looked very, very comfortable apart from that match against Dimitrov.

“They know each other’s games so well. It’s going to boil down to those details and moments. It’s a mouth-watering semi-final. It’s such an exciting match to look forward to.

“Djokovic has been getting the job done. They know each other’s games so well. Djokovic has the history on grass. Sinner is back in the semi-finals and has never gone further at Wimbledon.

“So it’s going to boil down to those details of who can hit the spots, who can get on top in the rallies, who can be dictating, and when they get the chances, who can get those breaks.

“You only have to be better than one player on a given day and Novak Djokovic was a little bit better than Flavio Cobolli, but I think when you analyse the performance Djokovic will know as well as anyone he’s going to have to raise his levels. When he analyses that performance, it was probably a 6.5 or 7 out of 10.

“When you go into a big semi-final that Djokovic has played on so many occasions, he is the type of player who really can turn it up and I think he needs to if he’s going to come out on top against Jannik Sinner.”
