Marshawn, he's hard to tackle. I only played against him a couple of times. We did OK against him in Chicago when I was there.
I was a naturally aggressive left-back, a cut-throat tackler.
You have to understand, it takes a lot of qualities to play linebacker - quickness, tackling ability and sheer force - so you just can't take someone from another position and think they could all of a sudden handle that role.
Rio Ferdinand is the hardest opponent I have faced - strong and quick. He didn't kick you. He was so classy. I could do all my step-overs, but he would watch the ball and tackle so immaculately. He only got the ball.
Lee Roy was the best college linebacker - bar none. He would have made every tackle on every play if they had stayed in bounds.
Julie Johnston is what I would call a loud central defender, as far as how she tackles and how she plays - you notice her. And you notice her in a positive way. She's a destroyer. She interrupts plays and tackles the crap out of people. That's a very visual thing.
Ledley King would get the ball off you without you even noticing he's the only defender in England who doesn't hold onto you, and he sometimes still gets the ball off my feet easily.
Oriol Romeu is very strong and doesn't lose possession much. He's a very complete player and makes good cover.
Timmy Horan was a childhood hero. He was a great distributor, elusive, good stepper, very physical, defensively very sound. What a rounded player.
Paul Scholes was always unbelievably talented. Quiet. And dirty. When he got his tackle right, it was a great tackle. But when he got it wrong, he could kill someone. He was so talented and a player I feel honoured to have played with.
