Don't understand some people, saying he done shit at other clubs and all that because the thing is, how are you suppose to put your heart into a team you really do not care about ? Knight cared about us and put his heart and soul into it and that's why he done so well.
I've always been a big fan of Knight and i don't see the harm of a trial. If Poyet see's what he likes then sign him, if he doesn't then don't and wish him the best of luck elsewhere.
