Former Chelsea midfielder Deco has heaped praise on current manager Jose Mourinho, saying that the Portuguese tactician is the 'best coach he ever worked with', reports the Daily Mail.
The 36-year-old Brazilian-born star - who retired earlier this year - was asked about the Blues boss in an interview with Barcelona-based newspaper Mundo Deportivo.
Deco, who moved to Stamford Bridge in 2008, also revealed how Mourinho tried to bring him to Chelsea following their successful spell together at FC Porto, but the Portugal international opted to join Barcelona instead.
"As far as strategy goes Mourinho is the best coach I have worked with," he explained. "He convinces you that if you do what he tells you to do it will bring results and it does.
"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."
Mourinho had already left Chelsea by the time that Deco arrived in west London, brought to the Premier League by Luis Felipe Scolari. He also enjoyed a spell under Scolari's replacement Carlo Ancelotti, who incidentally succeeded 'The Special One' at the Santiago Bernabeu in the summer.
And, though he looks back fondly on his time under Mourinho at Estadio do Dragao, there is an appreciation of all the other managers he has worked with, both at Chelsea and Barcelona.
"Scolari is another coach who convinces players with what he tells them. And I learned a lot of things about the 'Italian school' of playing from Ancelotti."
On former Barcelona boss Frank Rijkaard, Deco added: "I have never seen a coach, who having been a great player, was still able to put himself beneath his players. That is very rare in football."
