He's had a dip in form. I do worry about his confidence and how happy he is in general, but it's probably part and parcel of being a young player abroad.
I think we play better football with him in the team. But the way we are, we lack clinical finishers. And - in this league - strength. So I'd say we will get better results with Aguero.
If he goes by 2011, I'll be amazed. He's so very talented. I can't think of another forward around his age who has anything like that complete a set of technical skills.
