Tottenham boss Andre Villas-Boas has declared Real Madrid coach Jose Mourinho as the "greatest of all time".

AVB worked for Mourinho at Chelsea before launching a coaching career of his own.

"It was a unique experience. It is very difficult to find someone with such professionalism, dedication and knowledge of the game. Fortunately, I saw a good professional in observing the games and in the study of adversaries. It was a privilege to work with him and to know his training methodology," said Villas-Boas.

"Mourinho is perhaps the best coach of all time."
