His football might be the primary reason Whites worship the Argentine head coach, but the wit, wisdom and philosophy of the following memorable quotes have also played a part.
7. On supporters
"If there is something that makes this job very attractive it is when I am in contact with the passion of the supporters. We get paid, the only thing they get is emotions. This is why supporters are the best thing in football."
8. On the Premier League dream
"I am aware of this from the first day, that people desire this. What I can realise is the wish of the people of Leeds. I cannot feel that. How I manage this emotionally, our job has a rule - we have to win the next match."
9. On management stress
"I thought at my age maybe I could be more relaxed about the consequences of my job, but the opposite is true. I worry about what is going to happen. I always analyse but I feel harm when there is something not going well."
10. On the Chilean people
"I admire what the Chilean people are doing, the normal citizens. They take the democracy in a different way. They are an example for other countries poorly treated by their authorities. They claim in the correct democratic way."
11. On Hernan Crespo
"My goal is to publicly apologise to Crespo because I didnt tell him the truth. If you lie to your son in order that he gets something from this artificial moment of strength, the lie, you will have weakened him in the future."
12. On the ideal footballer
"Mental strength, sufficient ability on the ball, being bright and intelligent enough to interpret different styles of play. Strong physically and brave. A competitive spirit."
