Guardiola is expected to win a third Bundesliga title this season and Bayern remain in the Champions League but the coach will leave Germany in the summer to move to the Premier League.

"Pep will be whatever he wants to be," Alves told ESPN.

"He is like Neymar. They have such a capacity to reinvent themselves and a dedication to studying things. Obviously he has a gift, the gift of management. It has not gone bad where he has gone, and won't go bad this time.
"He left for Bayern, but I don't believe he liked it so much. He likes to revolutionise everything from the start. There he did not have that possibility, but he will now at City.
"He likes challenges - everybody else should get ready."
