Guardiola says they're hoping Aguero will agree to enter negotiations.
He said, "He's going to give us a decision. He's still not in his best condition. His injury was long. He needs to be so sharp, the quality to score in the box we don't have doubts but he need a bit of time, training sessions and the minutes he will have. After he has seven months ahead to show. He deserves with the club the fair talks to do what is best for him, for the club, for everyone.
"I was lucky to play as a manager with incredible players. He was one of these for sure. But as a human being, I've never found a big star to be like him."
