Serena Williams won her 21st Grand Slam title at Wimbledon on Saturday, defeating Garbine Muguruza of Spain. Sunday promises the long-awaited rematch between defending champ Novak Djokovic and Roger Federer, who's won the tournament seven times already himself.

Wimbledon 1980 was the ultimate showdown.
