Watch: 'You look like 40!': Carlos Alcaraz charms John McEnroe in Roland Garros gym moment

Carlos Alcaraz and John McEnroe had a fun interaction in the Roland Garros locker room this Wednesday, both using exercise bikes. McEnroe showed he still enjoys working out, positioning himself next to the Spaniard as they had a relaxed conversation.

Alcaraz is gearing up for his next challenge in the French Open semifinals this Thursday against Italian Lorenzo Musetti. The Spaniard boasts a 20-1 record on the clay swing and an impressive 12 consecutive victories at the French Open. He'll be looking to return to the tournament final when he faces the Italian, whom he has already beaten in recent months in both the Monte-Carlo Masters final and the Rome Open semifinals.

While Alcaraz prepared to return to the court for the semifinals, he was doing warm-up exercises in the Roland Garros locker room, joined by none other than former World No. 1 John McEnroe, who is participating in television broadcasts as a commentator for TNT Sports.

In a moment captured by Tennis Channel cameras, the two were seen chatting when Alcaraz mentioned to the seven-time Grand Slam champion: "I would like to be like you, you know?"

McEnroe gave him a serious look and replied, "Really old," then added, "How old is your father?" to which Alcaraz responded that his father is 54 years old.

"I'm 66," McEnroe said seriously, as both continued their workout on the bikes and Alcaraz couldn't help but smile. "You look like 40," the four-time Grand Slam champion responded.
