Sergio Aguero

When I moved from Independiente to Atletico Madrid, I was only 18, and I found it hard to adapt. But what surprised me most about moving to England was how fast the game was. I like it, but it is so quick.

I always got on well with Roberto Mancini and never had a problem with him. Every manager has their own way of working, tactics, and style of play. As a player, you do what the manager says. There are misunderstandings, but generally, everything was fine under Mancini.

As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.
