The 49-year-old enjoyed success in England at Chelsea from 2004 until 2007, and he has nothing but fond memories of his time in the English top flight.
"My memories from English football could not be better," Mourinho said ahead of the FA150 launch.
“In England you feel the real passion for the game. It’s not just about passion for clubs, it’s mainly about passion for football – and you feel it. I loved it from the first to the last day.
"But I know that one day I will come back because English football means a lot to myself."
Mourinho has an ongoing contract with Madrid, but a number of recent reports have suggested that he could leave the club at the end of the 2012-13 season.
