After surviving a tough match against Alex De Minaur in the fourth round at Wimbledon, Novak Djokovic had a funny reason why Monday's win meant more to him.

Roger Federer had a front row seat to watch Novak Djokovic come back in his Round of 16 Wimbledon match vs. Alex de Minaur on Monday afternoon. Djokovic advances to his 16th Wimbledon quarterfinals with the win.

The Serbian has now reached the quarter-finals at SW19 in 16 of his 20 visits, with this year’s run to the last eight including wins over Alexandre Muller, Dan Evans and Miomir Kecmanovic before coming from behind to beat Alex De Minaur in an entertaining Centre Court battle on Monday. He has dropped just two sets across those four ties.
