While he says he 'could' extend his deal he has vowed to definitely return to Argentina and the club where he started his career.
Tevez said: "At 28, I want to be in Boca. I have another year on my contract with Manchester and I could extend it for four years more then return.
"But I want to return to Boca at my peak not as some fatso. Imagine if you cannot move - they'd scream insults at you. If I return it will be to get stuck in and play!
"But I'd like to stay a few more years in Manchester. They look after me well."
