Tevez feels wanted again and he plans to repay the club by leading them to more trophies.
The ex-Manchester United hero said: "I'm returning feeling renewed. I'm really up for having a great season.
"I'm better now and only thinking about playing football. I feel useful and valued and that's vital for me.
"Now I feel settled at the club, I feel good in myself and I'm working hard, the main aim is to try to be champions again."
