Returning to Norwich in January 2010, he had made 15 appearances for the Underhill side. Barnet manager Paul Fairclough acknowledged: “We’d have him tomorrow if he was going to be allowed to come out on loan again. From my perspective, having just come in, he is certainly the type of player I like because he’s a passing full-back, he wants to play, wants to get the ball down, wants to join in with the play, and I’ve enjoyed him being here. I would have liked the opportunity to work a little bit longer with him, but I do understand why he has been brought back and we’d just like to thank Paul Lambert and the Norwich staff for allowing him to come out. It was very good of them and he’s been a real ambassador for the club.
