Chelsea manager Jose Mourinho has surprisingly revealed he "would return to Real Madrid" – even though he ended his tenure in La Liga on a sour note.

Earlier this week Chelsea chief executive Ron Gourlay revealed the West London club wanted the Portuguese boss to stay at Stamford Bridge for the next decade.

However the manager has refused to rule out a return to the Santiago Bernabeu, as he feels he has unfinished business having failed to win the Champions League during his three seasons in the Spanish capital.

"On one hand I achieved a goal: to win [the] three championships that I consider the most important in the world [England, Italy and Spain]. That goal was important" Mourinho said during an interview with Portuguese TVI.

"What if you could return again and join Madrid? Yes, definitely. It was an experience as a man and as a coach that I would repeat again without thinking twice."

Nevertheless, Mourinho admitted that, should he return to La Liga, he will do "the things different".

"If a coach can think and self-criticise, as I do, then the decisions that are made will not always be the same. Not only at Real Madrid but with all clubs."

Mourinho was said to have fallen out with a number of senior Real Madrid players such as legend Iker Casillas, Cristiano Ronaldo and Pepe.

But when asked whether his poor relationship with the dressing room was the reason behind his Real Madrid exit, he said: "You won't hear me talk about what happened in the past, whether it be positive or negative.

"I left Real Madrid with a fantastic relationship with the president, the executive director and the entire club after making a decision which was best for my career."

Mourinho insisted he is happier than ever at Stamford Bridge – even though he ended last season without silverware.

"I am a happy man, I am going to matches and training with great joy and I am not a person who likes to be talking about the past.

"This is the only time that I'm not thinking about the next stage of my career. Before I always thought about what would come next. Without being planned, I'm back. I prefer it as a place to work and for my family and social life. I returned here because the club has a different project. In my first spell Financial Fair Play did not exist."

However the Chelsea boss admitted he has no relationship at all with Manchester United legend Ronaldo, just days after claiming the winger prevented him from winning the Champions League during his time at Real Madrid – after missing a penalty during the shootout in the semi-final against Bayern Munich in 2012.

"The relationship does not exist. He plays for Real Madrid and I'm at Chelsea. We do not often pass each other on the street" Mourinho said. "The relationship doesn't exist, it's just a memory. I remember the good and the not so good. I remember that he is a goal machine, he helped me to become a champion, to win the cup and the Super Cup.

"He probably also helped him and each of us to make history in winning the league with 100 points against the best Barcelona side in history. Cristiano Ronaldo gives me great memories and I wish him all the best in his career, for his country and for his club, because when I go to a club I go with a sense of belonging and wish my former players continued success."
