"Diego is a forward and he knows that, in my idea of football, the forward must be a point of reference for the team. I don't like that a forward moves around the pitch. I like him to stay there [in the box] because you are a forward and your commitment is to score goals and to stay in the right position. You are a forward - not a midfielder, not a defender."
Good.
Hopefully this mean we done see costa trying to dribble past player on the wing.
