Toni Kroos has paid tribute to Real Madrid teammate Cristiano Ronaldo.

Kroos says CR7 is football "crazy".

"Cristiano is crazy for football. If he could just chose better timing for his parties that would be great (laughs). He works so hard on a day to day basis, determined to improve.

"He loves scoring goals. Only he can achieve what he is achieving. His hard work is all combined with his great natural talent."
