Roger Federer was back at Wimbledon, and back at Centre Court, on Monday — only this time, he was there to watch some tennis, not play it, at a place he won a men's-record eight championships.
The now-retired Federer sat in the Royal Box for his former rival Novak Djokovic's 1-6, 6-4, 6-4, 6-4 victory over Alex de Minaur in the fourth round at the All England Club.
