Manchester City boss Pep Guardiola is wary facing Wolves on Saturday.
City go to Molineux for the early kickoff.
Guardiola said: "It's a completely different team from previous seasons. They played five in the back with [Conor] Coady now they decide to play four. I am impressed with how they play.
"They have a lot of very good things in terms of central defenders having a good process, when they have attacks they can do it inside. They have a lot of talent. They are one of the toughest opponents for us and tomorrow will be no exception."
On potentially facing Diego Costa on his Wolves debut, he added: "Diego Costa has had an incredible career. His quality, the trouble they had with their striker [Sasa Kalajdzic] I am so sorry for him. So we will adapt in case he [Costa] plays."
