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, winner of four majors, crushed the Dane Holger Rune (6-4 and 6-2) in his first game and now will face Nadal in the semi-finals of the tournament with this set to be the last ever game between the two idols of Spanish tennis, with the Davis Cup in Malaga next month set to mark Nadal’s definitive farewell from the sport.

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."

Carlos praised his idol, admitting he sought a professional career after watching Rafa's matches while growing up. The young gun will try to enjoy the duel, although it will not be easy, considering it's the veteran's penultimate tournament in a career.
