He is a player who has played at the highest level and worked with the best managers in the game, lampard, Gerrard are all the same and they're getting a crack at it... don't get me wrong there is no guarantee he would be a success and tbh the mind numbing judgement of most villa fans wouldn't have the patience for it but I wouldn't rule it out....
But yeah Mellberg would be a better option as he's already a step ahead of Terry..
