Mourinho has won the treble at Inter Milan and La Liga with Madrid since departing Chelsea in September 2007 but the two-time Premier League winner has always said he felt happiest in England.
With Real Madrid slipping a full 18 points behind Barcelona at the weekend, and reports suggesting he will leave the Bernabeu at the end of the season, Mourinho has potentially alerted a number of clubs by again expressing his love for the English game.
In a special video message to mark the Football Association’s 150th anniversary, Mourinho said: "There could not be a better place to go. 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.
"My memories are great. I loved it from the first day to the last. I don't regret my last day because after that I was lucky enough to enjoy Italy and to have and enjoy some success there and also in Spain.
"But I know that one day I will come back because English football means a lot to myself."
Mourinho won the FA Cup in 2007 when his Chelsea side beat Manchester United in the first final to be held at the new Wembley, and he says the competition has a special place in his heart.
"I know what I felt when I had to go up the Wembley stairs to get the FA Cup," he said.
"The FA Cup represents the passion of football. It represents clean football. It represents the good smell of football.
"If you are in England, you feel it. You feel proud to be in football - even in the worst moments.
"That's pure football. That's the football you play as a kid in the street transported through time and space into organised competition and into the real world of football."
