The midfielder was outstanding on the day.
Zidane enthused: "He had a great game and deserved it. He got the three points for the team with his second goal. I´m happy with how he played and with the whole team´s performance. He made the difference, I´m happy and Real Madrid is the place for him. Now we have to rest and think about Tuesday's game.
"His goals handed us the three points, particularly his second. He could have got a third following an excellent piece of play. I'm delighted for him. He's got the character to go out and do what he did today. He's a great player and he's proving that. When a player gets two goals and makes the difference you might say that it's his best performance, but I think that he has already put in many good displays. This is just the latest in a number of very good performances."
