Novak Djokovic reached his 14th Wimbledon semi-final from the 20th trip to the All England Club. The veteran stopped the clock once again but could not challenge world no. 1 Jannik Sinner for a place in his seventh consecutive title clash in the cathedral of tennis.

Djokovic and Sinner's similarities make their matches especially compelling. For the coach who taught them both, it is no surprise.

Fast forward to his semifinal against Jannik Sinner, and something pretty unexpected happened on court: Sinner actually apologized to Novak about that fall when the two met at the net following match point. And of course, in true Djokovic fashion, he had the classiest response that’s got everyone talking about his sportsmanship.
