Jose Mourinho admits he still has unfinished business at Manchester United following his dismissal last year.
The 56-year-old was sacked as United manager last December following a troubled start to the season which saw the club struggle for consistency.
Mourinho’s final few months at Old Trafford were also tainted by a high-profile falling out with Paul Pogbawhich saw the France international stripped of ‘second captain’ duties and regularly out of the starting line up.
And although the former Chelsea manager insists he gave his all at United, he still thinks there is more he could have achieved at the club.
“The only club where I feel that (unfinished business) is in relation to Manchester United,” he told beIN Sports.
“The moment I left with what I think I could have achieved and the improvement of a few things but all the other clubs I have the best possible feeling, which is I gave everything.”
Mourinho also spoke about the struggles facing any modern manager regarding how they handle the treatment of players who are unlucky with a lack of playing time.
The Portuguese coach continued: “I think the thing that normally is crucial and I’m thinking about all these things in the two months I’ve not been working.
“You try to always to find solutions for the problems, there is one problem that I cannot find a solution which is – when the player is playing he likes the manager, when he’s not playing he doesn’t like the manager.
“This is something basic that you can try to control a little bit, but that’s the nature and that nature you’re not going to change.
“They play, they are first-choice players, they like you very much, if they don’t play, they don’t like you very much. This is the basic thing you cannot change.
“Then, I think it’s about like in every job in the world with human beings, we like some people more than others. That’s normal.
“It’s the personality, the way of being, the way of thinking, you have more chemistry, empathy and chemistry.
“And that’s why some players are phenomenal with one manager and with another not so good. It’s chemistry.
“And one of the things I want to analyse and detail and to try to understand this situation better, you need to care more about the relations with the ones you don’t like.
“Because the ones you like and the ones who love you, you don’t need to feed it every day and every moment because it’s something you have for granted. Human nature is human nature.”
