Former Chelsea midfielder Deco rates Jose Mourinho the best coach he's worked with.
Deco has announced his retirement after a glittering career.
Deco said: "As far as strategy goes Mourinho is the best coach I have worked with. He convinces you that if you do what he tells you to do it will bring results and it does."
Deco was asked about the Chelsea manager in an interview with El Mundo Deportivo.
He said: "Working with Mourinho was incredible. I learned so much. It was a long time ago and some people say he has changed a lot, others that he hasn't changed at all.
"He turned Madrid into a very effective team. They were different to Barcelona aesthetically but in terms of efficiency they were very effective.
"For everything that they say about him, he put Real Madrid at the same level as the best ever Barcelona side."
