Watch Sagna...No, in the formation we play the full backs are encouraged to get forward as much as possible, Kolarov is doing what his manager tells him. I thought Sterling had a decent game tonight, yes there are parts of his game that need some work but surely no-one thought that a 20 year old was the finished article?
He offers the support he offers the width, he offers an option. He let's the winger have the option to go one on one with the opponents fullback. He offers the overlap when it's needed and when he can. Basically he plays with a brain!
