Carlos Alcaraz likely just played his tennis idol Rafael Nadal for the last time in their professional careers during Thursday's semifinal match of the Six Kings Slam. Although the score makes it look like Alcaraz ran away with the match at 6-3, 6-3, the 21-year-old admitted he still had to play his best in order to beat the 22-time major champion.

Carlos Alcaraz sent an emotional message to Rafael Nadal after beating him in their final singles match on October 17, Thursday. Nadal will retire from tennis after the Davis Cup.

During an interview at the ‘Six Kings Slam’, Alcaraz was asked who has a better forehand between him and Nadal: "I am only starting my career, so for now I choose Rafa's. For now, but I am very happy with my forehand as well, so we will see at the end of my career who has the better forehand."
