Although Man United are not the side they were under Sir Alex Ferguson, Jose Mourinho has brought some much needed stability to the club.

The Portuguese manager may have had a mixed season last year, but his side have shown early promise this term, having gone unbeaten in their opening eight Premier League games.

Mourinho has been known to jump around from club to club in the past, having only spent a maximum of three years at one club.

But earlier this year, he announced to ESPN that he was ready to break that trend and stay in Manchester for the next 15 years.

He said: "I am ready for the next 15, I would say. Here? Yes, why not?

"After David [Moyes] and Mr. [Louis] Van Gaal, I come to my second year and hopefully I can stay and give that stability that the club wants.

"I will try, but again, I will have to try to deserve that, but that's what I try every day that I work."

This would have come as great news for Man United fans, who would have been relieved that Mourinho was committing his future to the club.

But, just three months on after announcing he would be there for the next 15 years, the former Real Madrid manager has now explained that he is sure that he will end his in Manchester.

Speaking to French TV station TF1, per The Mirror, Mourinho stated: "What I can say is that I am a still a manager with worries, with ambitions, with the desire to do new things and I don't believe... I am sure that I will not end my career here."

Although Mourinho is happy at the club for now, his comments that he has a 'desire to do new things' may be cause for concern for United fans.

This desire for new challenges has led to managing eight clubs in 17 years, and these comments hint that he may move on sooner rather than later.
