The Portuguese boss sparked some fears in the United hierachy when he said publicly that he would not retire at Old Trafford, as well as hinting at a future move to Paris-Saint Germain.
Mourinho still has 18 months left on his current deal with the Red Devils, with the option of a further year which would take him to 2020.
The Manchester club are reportedly keen for the 54-year-old coach to stay much longer than his current contract, with 'Daily Mail' suggseting that they want him to stay for as long as a decade.
However, this seems unlikely given Mourinho's comments to French publication 'Telefoot', during the week.
According to the aforementioned source, the club will commence talks over a new deal in the coming months, following United's positive start to the season which sees them just two points behind rivals Manchester City at the summit of the Premier League.
