"I knew that he was a quality player, but what has surprised me is that he was very physical. I couldn't believe how much he liked to get involved when he first joined.
"He is very strong and doesn't avoid any contact, not even in training with his mates at Liverpool. In fact, he's one of the players who kicks me always.
"I tried to prepare him for the strength in the Premier League as much as possible but I think he always had it in him - he's a bit of a hard man.
