He told liverpoolfc.tv: "He is always trying to improve. People probably don't realise how much he looks at his own mistakes and tries to sort them out. He wants to be the best player in the world. It's that commitment, that unselfish personality, which makes him the player he is.
"He's already in the top three players in the world and of course he can be the best one day because he's still only 25. He has so much potential and is at the best club in the world. I would like to look like him as well! He takes care of himself!"
