The former Tottenham star has stepped up in the absence of Cristiano Ronaldo to get Real back to winning ways.
He said: "I don't think I've changed much. The style in Spain, in comparison with the Premiership, is based more in keeping possession, but my style of play hasn't changed much. I'm very comfortable here."
Which of his team mates has impressed him the most?
"I can't pick just one person. Everyone here has impressed me and I've enjoyed every minute. It's amazing to be able to train with world-class players on a daily basis. It is helping me lift my game and makes everyone a better player. I love training everyday and I try to improve all the time as a player."
