The Spaniard scored just 12 goals in 44 games under the Special One last season but is adamant the two men enjoyed a productive professional relationship
Fernando Torres insists he learned a lot from Jose Mourinho in his final season at Chelsea.
Torres ended a disappointing three-year stay at Stamford Bridge last month by agreeing to join AC Milan on loan for the final two years of his contract, where he will replace the departed Mario Balotelli.
Mourinho frequently criticised Torres and fellow strikers Samuel Eto'o and Demba Ba last season and the lack of a reliable goalscorer was widely perceived to be the main reason why Chelsea fell short in the Premier League title race.
The Spaniard scored just 46 goals in 172 games for the Blues after joining for €62 million from Liverpool in January 2011 and netted 12 times last term under Mourinho, but is adamant he enjoyed a productive working relationship with the Special One.
"I had a professional relationship with him," Torres told reporters. "I learned so much.
"When I told him that I was going to Milan he wished me good luck, and he told me about the passion for football that is here.
"I wish him all the best, as he has done with me."
Milan CEO Adriano Galliani admitted it was "better late than never" to have signed the striker after he failed to tempt him to San Siro in 2004.
"Fernando is an incredible champion," he said. "He has won everything there is possible to win.
"Fernando began his career in Madrid, and even then it was clear that he was something special.
"We tried to get him in 2004, but that did not go ahead. But it's better late than never! We are happy to have him here and I'm sure he will do well."
