Roger Federer has made a return to Wimbledon — but to watch, not play, tennis. The eight-time champion at the All England Club sat in the Royal Box during his former rival Novak Djokovic's four-set victory over Alex de Minaur in the fourth round Monday.

The Serb trails only Roger Federer (39 years and 10 months in 2021) and Ken Rosewall (39 years and seven months in 1974). Competing in the Wimbledon quarter-final after turning 38 speak volumes!

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.
