Khedira rates Mourinho the best coach in the world.
"In my opinion, he is the best coach I have had and I cannot think of anyone better, because he helps all his players to improve. He always wants the best, he finds each player's strong points and that is what has happened with me. I used to be very impulsive and he got rid of that side of my game. Now I play in a calmer, more intelligent way," he said.
