Jermaine Pennant who is probably a millionaire? I'm guessing most parents of ten year old footballers will happily take that. If a big club comes along with better facilities, you're going to take it and believe you're good enough.
I agree Grant has his head screwed on the right way, but I don't think he helps your argument. He signed for Forest I'm guessing because the money was better and could have easily been a fringe/reserve player for the next 3 years.
