Real Madrid No2 Karanka heaps praise on Modric for victory over Athletic Bilbao
The former Tottenham midfielder was outstanding during the victory.
Karanka said: "When we signed Luka we knew which positions he can play in and he is adapting to what his team needs. Everyone knows the quality he has and with a team like this he is going to get better. Today made a great pass to Karim for the first goal and every day he is getting better."
