WATCH: Carlos Alcaraz almost jinxes Spain, himself with hilarious Centre Court gaffe

Moments after booking a spot into his second consecutive Wimbledon final on Friday, Carlos Alcaraz committed a rare unforced error.

The Spaniard was on song in his absorbing semifinal clash against Daniil Medvedev, rallying after losing the opening set to record a 6-7 (1) 6-3 6-4 6-4 victory on Centre Court.

Alcaraz booked a place in Sunday’s championship match against Novak Djokovic—which is scheduled to take place only a few hours before Spain and England go head to head in a blockbuster showdown for the 2024 European Cup title in Germany.

The 21-year-old couldn’t resist a cheeky joke to the crowd, as he highlighted his country having a challenger in each final:

“I feel like I’m not new anymore,” he said when asked how he’ll prepare for Sunday. “I know how I’m going to feel before the final, I’ve been in this position before. I will try to do the things that I did well last year, and try to be better.

“It’s gonna be a really good day for Spanish people, as well, with the Euro Cup…” (Watch video above)

Before he could even finish his sentence, the mostly English crowd on Centre Court let Alcaraz know what they thought of his prediction as loud boos and whistles erupted. Besides the fact that Spain was playing England in said final, Alcaraz himself still had a match to play—against the seven-time champion and former world No. 1 Djokovic, no less.

Alcaraz, grinning, handled the moment with class as held up his hands in apology and quickly clarified: “I didn’t say Spain is going to win! I just said it’s going to be a fun day.”

The Spaniard famously has a close relationship with players from his national team, including striker and former Real Madrid player Alvaro Morata. The pair have even created a sort of pre-match ritual for good luck at Wimbledon and Euro 2024, too.

“I've spoken to a few players since Euros started this week... We send best of luck in every match,” Alcaraz revealed. “Obviously we (will) send the best of luck on Sunday.”

Alcaraz also gave a shoutout to a special guest in his player box, after putting on a show against Medvedev under the watchful eye of Real Madrid and Croatia legend Luka Modric.

“Luka is a really nice person. We've met a couple of times… He wanted to come, and for sure I admire him. There's always going to be a spot for him,” Alcaraz said.

“Amazing guy, amazing athlete that I admire a lot. It's great to have him in the box supporting.”
