Rafael Nadal will begin make-or-break new treatment on his chronic foot injury next week which he hopes will save his career.

The 36-year-old won his 14th French Open on Sunday with a comprehensive defeat of Norwegian Casper Ruud.

But Nadal revealed he has only been able to play at his favourite event by taking anaesthetic injections before every match to numb his foot, a procedure he is not willing to continue.

Should the new treatment, radiofrequency ablation to the nerve in his foot, not work then the Spaniard admits he will have to consider surgery, casting major doubt over what remains of his glittering career.

However, should it prove successful, Nadal says he intends to play at Wimbledon, which begins in only three weeks.

"It's obvious that with circumstances that I am playing with, I can’t and I don’t want to keep going, so the mindset is very clear," he said.

"I was able to play during these two weeks with extreme conditions. I have been playing with an injections on the nerves. That’s why I was able to play during these two weeks, because I have no feeling in my foot.

"Everybody knows how much this tournament means to me, so I wanted to keep trying and to give myself a chance here. But it’s obvious that I can’t keep competing with the foot asleep.

"So that’s the thing that we are planning to do the next week. It’s going to be a radiofrequency injection on the nerve to try to burn the nerve a little bit and create the impact that I have now on the nerve for a long period of time.

"That’s what we are going to try. If that works, I’m going to keep going. If not then it’s going to be another story. And then I’ll ask myself if I am ready to do a major thing, a major surgery that doesn’t guarantee me to be able to be competitive again take a long time to be back.

"Hopefully it works and can take it out a little bit the pain that I have. If that happens, let’s see if I am able to keep going for the grass season.

"I’m going to be in Wimbledon if my body is ready to be in Wimbledon. That’s it."
