The Barcelona centre back has found it difficult to play often for the club recently as he struggles with injuries.
“I never considered going to Milan. I want to stay with Barca. My idea is to continue here. I have three years left on this contract and if I can, I will prolong that further.
“I have always said that I want to play until my 40s, but if I still have discomfort then I will have to stop.
“If I am not right, I will not fulfil my contract, I will go, I will thank everyone and leave. I am trying to return as soon as possible, the knee rules the decision.”
