I think that's from his interview with Graham Hunter on the big interview podcast. I listened to 5 minutes of it before, he also claims if Ben Arfa had've scored to go 2-0 up against Benfica we would've won the Europa League as we 'dominated' Benfica. The early part of the interview is about how he wasn't happy with the lack of technical work they did when he got his coaching badges, he speaks as if he's some sort of coaching genius. It's a tough listen.
