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.

The win marked the 16th time Djokovic has moved into the quarterfinals at Wimbledon. The event has been his second-best Grand Slam over his career. Djokovic has seven wins at Wimbledon, and has played in the final at the event in each of the last six Wimbledons.

Novak Djokovic came back from a set down to beat 11th seed Alex de Minaur on Monday. Roger Federer watched the Serb's win from the Royal Box on Center Court.
