Rafa Nadal will have one last chance to face old rival Novak Djokovic before the Spaniard calls time on his illustrious career with the pair set to meet at the Six Kings Slam exhibition event in Saudi Arabia.

Rafael Nadal starts his pre-retirement farewell tour against Carlos Alcaraz on Thursday at the Six Kings Slam, and Novak Djokovic faces Jannik Sinner at an exhibition event that awards money but no ATP ranking points and is Saudi Arabia's latest foray into tennis.

He was not invited to compete at the Six Kings Slam this week, where Novak Djokovic, Rafael Nadal, Carlos Alcaraz, Jannik Sinner, Daniil Medvedev and Holger Rune battle it out for £4.6million. Each participant receives at least 1.15m, which Medvedev picked up in just 69 minutes after being dismantled by Sinner in the quarter-finals.

Novak Djokovic and Rafael Nadal, who own 46 Grand Slam singles titles between them, will be among the tennis stars competing for the largest purse in tennis history.

In a recent interview with DAZN Sport, the 22-time major champion was asked to push the conversation further and compare the rivalries between him, Federer and Djokovic to the new rivalries being made between young players in tennis—like the battles between Carlos Alcaraz of Spain and Jannik Sinner of Italy.

Tennis wonderkid Justin Engel has pleaded with Novak Djokovic to avoid retirement for the time being. The German recently followed in the footsteps of Carlos Alcaraz by becoming an extremely young winner on the ATP Tour and he wants to face idol Djokovic before the tennis icon bows out of the sport.

Rafael Nadal will have one final battle with Novak Djokovic when they meet in the Six Kings Slam exhibition event on Saturday. The Spaniard is retiring after next month's Davis Cup finals in Malaga, bringing the curtain down on an incredible career.
