Ronaldo has hinted his illustrious career might be at an end, although he is still hoping to kick a ball again.

The Milan striker’s season ended recently after rupturing a tendon against Livorno.

The 31-year-old, who is the all-time leader scorer in World Cup finals, is looking at a lengthy spell on the sidelines before resuming training.

Ronaldo is keen to play on and is currently focusing solely on his recuperation, although he is not ruling out hanging up his playing boots altogether.

“My heart tells me to play again, but my body is sending me signs of fatigue and suffering,” said Ronaldo.

“It’s been a real knock-out blow, both physically and mentally. I still don’t know what happened.

“I still mustn’t think about playing again. I must focus for the moment on undergoing the best physio possible.

“If I’m okay at the end of that, then of course I’ll play again. If there’s another ending, it will be a difficult and sad decision.”
