Carlos Alcaraz's coach reveals edge he has over Jannik Sinner after his private request

Carlos Alcaraz's coach pinpointed the Spaniard's "chameleon-like" training style as the reason he was able to edge out Jannik Sinner to the US Open title on Sunday. Juan Carlos Ferrero, who has been Alcaraz's coach for six years and throughout all six of his Grand Slam victories, believes that the 22-year-old's specified preparation for the final major tournament of the season is the reason why he succeeded in winning the title.

Alcaraz beat Sinner 6-2, 3-6, 6-1, 6-4 to secure his sixth major title in tennis, and exact revenge for his Wimbledon final loss against the Italian ace. Ferrero told the media after the US Open final that he instructed the young star to change little things in the build-up and also during the final, which Alcaraz succeeded in doing with ease. He said: "The most incredible thing about Carlos is that he is so good at quickly correcting the small details he needs to improve."

Describing his adaptability to change at the drop of a hat, Ferrero added: "He is chameleon-like, and you can ask him to do anything during a match, he adapts and ultimately succeeds, and we also transfer that a lot to training."

Following his four-set loss to Sinner in the Wimbledon final, putting the Italian just one Grand Slam away from matching his total, Alcaraz and his coach set off to embark on a special training camp to prepare for the final major tournament of the season.

Ferrero explained: "I asked Carlos Alcaraz for certain new things in preparation for the upcoming matches against Jannik in particular. In just 10 days, he improved considerably."

The pair sat down and analysed both the Wimbledon and French Open finals against Sinner, to "try to see the little things that could be improved."

After this strict preparation, Ferrero admitted that Alcaraz was "perfect" throughout the US Open final as he took down his direct rival in just two hours and 42 minutes. Noting the battle forming between the two young tennis stars, the former world No. 1 believes the duo are a lot like the early days of Roger Federer, Rafael Nadal and Novak Djokovic.

Alcaraz was also proud of his own performances during the US Open, saying he played "amazing tennis" throughout the final major tournament of the 2025 season to secure his second Grand Slam title of the year. The 22-year-old said: "In general, I think it has been my best level during the two weeks. Since the first match until the final I think I've been playing great tennis.

"The focus was really, really high. I didn't lose the focus at all in any of the matches, which I'm really happy about. With the serve, I've been really focused on it. I got broken just three times, once in the final. In general, I just played amazing tennis."

Reflecting on his gameplan against Sinner, Alcaraz added: "I just maintained my best level since the first game until the last one. Tactically, I tried to be perfect. Matches against Jannik are all about being good tactically, and physically it's really demanding as well. I think I have to be perfect against him.

"Today, I just was brilliant, to be honest. In the second set, a few mistakes, but in general, I just was brilliant. If I want to beat Jannik on the biggest stage, I have to be brilliant, which I'm really happy about."

Alcaraz now takes his Grand Slam total to six, with two French Opens, two Wimbledon crowns and two US Open titles - with just the Australian Open to claim out of the major tournaments. The Spaniard has also secured the world No.1 title with his US Open win, dethroning Sinner.
