Former Real Madrid defender Francisco Pavon is delighted seeing Aitor Karanka succeed as coach.
The pair came through the system at Real.
"He has a great responsibility and is doing very well. He is learning a lot with Mourinho and will be one of the best," Pavon told Marca.
"He was a person who always helped me, although we played in the same position. He is serious when he needs to be serious and fun when he gets the chance."
