Manchester City boss Roberto Mancini feels it will take Sergio Aguero to adjust to Premier League football.
Mancini also has left the door open for Carlos Tevez to come back and team up with Aguero for a title push next season.
The Etihad chief said: "Sergio could play with Edin Dzeko, with Mario Balotelli or with Carlos.
"Sergio is a top player and he's only a young guy. He's scored a lot of goals and I expect him to score a lot for us.
"He needs to get to know the Premier League because it's so different to La Liga.
"But I think after two months he will understand the game here and will score goals and win trophies with us."
