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.

The Davis Cup Finals - which will take place in Malaga in November - will have an even deeper meaning this year. Rafael Nadal will say goodbye to professional tennis at this very event, where he will have the chance to represent his country for the last time in his legendary career.
