Actually, he's fighting with Ryan Giggs, one of the finest wingers in the game (for all his glorious inconsistancy), for the left wing. Sometimes he plays on the right, but even that may become a struggle with Solskjaer returning from injury.
I'm willing to give Ronaldo time to mature before making a judgement, but for now, he's just a kid with glorious technique, not a star. Kaka appears to be a real star in the making. I can't wait to watch him live in Dublin!
