Middlesbrough boss Aitor Karanka is a big fan of Arsenal midfielder Santi Cazorla.

Karanka has followed Cazorla since his time with Villarreal.

He said: "He has everything. I think he is one of the best, not just here, I think he is one of the best in the world as a technical player.

"He is the kind of player you don't know if he is left-footed or if his is right-footed. He understands football perfectly. I have known him for a long time. For me, he is their best player."
