They dont mention it anywhere. When Berbatov uses the outside of his foot when really he's better off using his left foot, its fine, its classy, whatever.
If Valencia does it, complaints. Just trying to understand where people are coming from as I dont think a winger needs to be two footed more than a striker. So if its fine for one player it should be fine for the next. Thats not to say Valencia shouldnt come inside more often, he should, but thats exactly what he did to get his chance to use his left foot today. He should have done a bit better with the shot and ideally would have used his left foot. But using his right and getting it on target would have been fine too.
