However, only three men have pushed the defending champion to a fifth set during Djokovic's 33-match winning streak at Wimbledon. Rafael Nadal (2018), Roger Federer (2019) and Sinner.
"It means a lot to me. Obviously, there is a lot of work behind this. Very happy that I can play my first semi-final here in this special place, a special surface," said world No.8 Sinner, breaking new ground in Grand Slam play this fortnight.
"For sure physically I have improved. I'm much stronger. I can stay on court for many hours without suffering.
"Also mentally you're going in a slightly different mental side on court knowing you are also Top-10 player.
"I think also game-wise or tennis-wise I feel better. If I have to play the slice, I can play now without thinking… I can go to the net knowing that I have good volleys. I have some good things now in my game, and hopefully I can use it in the right way."
