Watch: Carlos Alcaraz goes from hero to villain after Wimbledon semifinal win

Alcaraz's Wimbledon title defense is expected to start a few hours before the England versus Spain soccer match. However, if his match were to give sets, Alcaraz might still be on the court when his country battles against the Three Lions at the Olympiastadion in Berlin.

The Spaniard is trying to become the first multi-time Wimbledon champion outside the "Big 4" in the 21st century. On Friday, he became the first since Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray to make the final of the French Open and Wimbledon in the same year in a quarter century. 

Widely hailed as Nadal's heir apparent, Alcaraz is on a similar trajectory as the 22-time major champion at this juncture of his career. At 21, he has already won three majors, getting off to a start comparable to Nadal's in the mid-2000s. 

A fourth major win on Sunday would cement him as the flagbearer of the post-Big 4 era.
