The Portuguese boss has today seen his odds of leaving by 25th December cut from 3/1 to just 5/2, while even-money says he's gone by the end of the season.
And in a recent poll ran by Ladbrokes, a staggering 74% of fans believe Mourinho should leave the club as soon as possible.
Alex Apati of Ladbrokes said: "There's been a huge shift in the betting at Man United on Deadline Day, but it's nothing to do with incoming players. Instead, Mourinho is now looking more likely than ever to leave the club in the next few months, something which is clearly what the majority of fans want."
