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!

Novak Djokovic may not have the serve-and-volley chops of Roger Federer, but he threatens to eclipse him as the most accomplished player in Wimbledon history.
