The pair meet in the semi-finals of the Six Kings Slam, an exhibition event being held in Saudi Arabia.
Each of the six players competing will take home a guaranteed £1.15m, with the winner picking up £4.59m, more than has ever been on the line at an event in the sport’s history.
Nadal and Novak Djokovic were both handed byes through to the semi-final, while Alcaraz joined them in the last-four after beating Holger Rune 6-4 6-2 on Wednesday.
Nadal and Alcaraz have played each other three times, with Alcaraz beating his idol for the first time in their most recent meeting, in Madrid two years ago.
