Barcelona boss Pep Guardiola rates Real Madrid rival Jose Mourinho the "best coach in the world". Guardiola made the claim when discussing what makes a great coach.

"It is not necessary to have played football to become a great coach," he said. "Arrigo Sacchi changed this sport without having played and Jose Mourinho is probably the best coach in the world.

"Having been in a dressing room gives you advantages in certain situations, but not having been in one also gives you other advantages.

"This is life, as a player I did not have any physical aptitude that stood out, but I survived: I strengthened other aptitudes."
