How many times has Duff played at left back in his career for you to make that judgement?
out of the two, who is the better attacker?
out of the two, who hasn't disgraced himself time and time again at LB?
No man, try answering a question
Duff's played LB twice for us I think, he did ok. And surely most would rather sacrifice his attacking ability than N'zogbia's.
What is it with you and stupid arguments mate?
