Real Madrid midfielder Xabi Alonso has hailed the professionalism of Cristiano Ronaldo. Ronaldo is in superb form ahead of tomorrow's El Clasico.

"He is the most ambitious player I have met, with the hunger and desire to score in every game. He is impressive in terms of his athletic qualities and his technical abilities," the midfielder told Uefa's official website.

"He is a complete player: he has a great shot; he knows how to put his opponent off balance in one-on-one situations; he's great at finding space and he has great timing."
