I think while Duff has added a sense of defensive responsibility to his game I also think that this has been to the detriment of his attacking play which is the reason he was so highly thought of and also why Chelsea paid as much for him as they did. When Duff played in the U20 World Cup in Malaysia he was voted as the best European player at the competition and at the World Cup in Japan he was voted on to the tournament 11. So he has been a great attacking player in the past and he can be again, but not under Mourinho. He has done what any other player would do, he has adjusted his game in order to fit into the system and style of play that the manager prefers. I don't blame Duff for this, as I said any player would do the same. It's just that I think were he to play for a team like Barcelona or Real Madrid we would see his real attacking potential fulfilled. When Duff's career is over in 10 years or so it is quite possible that he will be remembered as nothing more than a Premiership grafter, a hard working player who occasionally was able to beat a man. If he gets to play for a big team, under a different manager, he could be remembered as much more than that. I know he has won the league with Chelsea and if he stays with them he will no doubt win more trophies but surely if he does move it will be to one of the bigger clubs where he does not necessarily have to sacrifice his ambitions while also being allowed to play his natural attacking game.
