Problem is that England U21 does not mean he will have a bright future. He has had a half premiership season where he has been good, but we have seen this many times with many players before. I am not saying that he will be crap, but I just think its a gamble that is too big with the ridiculous prices that is quoted in the papers.
Remember that Whittingham has 15 U21 caps, compared with Young's 4. History is full of U21 players that failed and never became more than Championship material. History is also full of young kids that impress in their Premier League debut season, but soon fade away into the Championship.
