Jose Mourinho has admitted his ties with Chelsea will never be entirely severed, but he has warned his old club that his heart is now with Manchester United

Mourinho will return to Stamford Bridge to face Chelsea for the first time since the club sacked him last December on Sunday, with his Manchester United blazer confirming he is now in the enemy camp for Blues fans.

“There is one thing that Chelsea fans can be sure of now: I am Manchester United 100 per-cent,” he said.

“I want to win with United and make them the best but I will always be respectful to Chelsea and it doesn’t matter what happens, I will never lose that feeling of respect towards the club.

“I have loved every club that I have worked for. I have this professional heart that makes me connect 101% with my club. When I was growing up in Portugal, I was not born a Porto supporter, but I still gave my life to Porto.

"I gave my life to Madrid, I gave my life to Inter and I gave my life to Chelsea. Now I give my life to United. That is my professional nature."

Mourinho admits he needs to bring success to United to build the same rapport he enjoyed with Chelsea fans, as he accepts trophy wins are required to secure a legacy at any club.

“Connections start before titles are won, but it is success that brings empathy between supporters and managers and makes that connection become really strong," he added.

"I have a three-year contract with United and if I am here for three years the people will know that I have given everything to the club and that I am a professional, dedicated coach who gives himself 24 hours a day to United.

"But if at the end of the three years I haven’t won a single piece of silverware for them, they will say ‘great guy, good coach, we like him, but we feel nothing special about him’.

“Chelsea have won four Premier League titles in their history. Three of them were won with me and the other one was won by the team I left behind.

"I took them to Wembley, I took them to Cardiff, I took them to cup finals. So there is a connection based on empathy – but built on success.

“In the end, when my last two or three months at the club were a period of bad results, the fans kept that empathy and remembered our relationship.

"That is something I don’t forget. And that is something I will always be grateful about because, with me, they have always behaved in a fantastic way.”
