I can say without any doubt that Robben is a left-sided player who can do the center as well - if he plays on the right, it's just a show of how much class he has. And, to my mind, Chelsea still are to get the best out of him. He scored like a madman for Eindhoven. I think the world of him - if I had Robben in my team, I wouldn't buy Ronaldinho - while Ronaldinho is a bit better, the two do the same thing and you can spend your money elsewhere.
I think Chelsea's buying plan goes like this: Ooh, lookie, this guy is quickly becoming a superstar! Buy him at whatever cost! Hmmm... how do we fit him into our side...
