Djokovic has won 24 Grand Slam titles, but this one would surely be the most remarkable of them all if he could defeat Alcaraz on Centre Court.

The Serb had to withdraw injured from May's French Open before his quarter-final after suffering a medial meniscus tear in his right knee.

Djokovic underwent surgery in early June and his participation in this tournament was in doubt. Yet now he is just one match away from not only equalling Roger Federer's tally of eight Wimbledon titles, but also surpassing Margaret Court's total of 24 Grand Slam championships.

"There was plenty of doubt," admitted Djokovic. "I came into London eight days before the tournament started. I didnt know [if I would play] and was keeping everything open until the day of the draw.

"I played a couple of practice sets with top players and that proved to me I was in a good enough state to not just be in Wimbledon, but to go deep into the tournament. That kind of mentality is there and is ever present. Thank you to the team members for helping me."

Djokovic was playing for the first time since Monday when he beat Denmark's Rune in the last 16, but then accused some of the fans of disrespecting him.

Some supporters were chanting the Dane's name, but stretching out the start of it, with Djokovic saying it was used as an opportunity to boo him.

There had been fears the same thing might happen on Friday, using Musetti's name, in an attempt to unsettle Djokovic. But the match was largely played amid a wonderful atmosphere with both players receiving plenty of support and applause when merited.

There threatened to be a flashpoint in the third set when a point was challenged, with Djokovic unhappy, and a delay to the action led to some boos heard from a few fans.

But the situation was soon dealt with, before Djokovic glared at a fan who called out when he was playing a shot shortly after he had just failed to take a match point. Again, the tension quickly passed as the match was played to a conclusion.
