Spain's Carlos Alcaraz had the Wimbledon crowd in his corner after he defeated Daniil Medvedev in Friday's semifinal.

Then the defending champion brought up soccer.

Alcaraz was cheered in the post-match interview when it was mentioned that he would be Esthengoing to the Wimbledon final - on Sunday - for the second year in a row.

But the boos rained down when he later said, "It’s going to be a really good day for the Spanish people as well with the Euro Cup."

England and Spain are playing in Sunday's final of the UEFA European Championship, so that didn't go over well with the Wimbledon crowd in London.

"I didn’t say Spain was going to win," Alcaraz responded diplomatically. "I was just saying it was going to be a fun day."

Alcaraz, 21, lost the first set to Medvedev but won in four sets, 6-7 (1), 6-3, 6-4, 6-4.

He will face either 24-time Grand Slam winner Novak Djokovic, who he beat in last year's final, or Lorenzo Musetti. Those two were playing in the late semifinal.
