Rafael Nadal is unsure if he will be fit to take on Roger Federer in the semi-finals at Indian Wells on Saturday after struggling with a knee problem in his quarter-final win over Karen Khachanov.

The 32-year-old required treatment on his right knee during the 7-6 (7-2) 7-6 (7-2) win over his Russian opponent, while Federer made relatively light work of Hubert Hurkacz.

The old rivals have not played against each other since 2017, but Nadal has hinted that he could pull out of the semi-final if his knee has not sufficiently recovered.

Of course my goal and my idea is to be ready, I cannot guarantee how I will feel when I wake up tomorrow. ‘But the desire to play a match like this against Federer is always very special, and it’s even more special if we’re both at a high level and at 100 percent.

Hopefully it will be that way, above all for me but also for the fans on site and for fans in general. I hope I will be able to play aggressively. ‘I need to be ready to react very quickly and to have everything in place to be able to succeed. If not, it will be very difficult.

Federer, who has won his last five meetings against Nadal, does not believe his recent record will count for anything should they meet again on Saturday evening.
