Former Manchester United winger Lee Sharpe believes Jose Mourinho is living on borrowed time at Old Trafford and expects him to be gone by Christmas.
United's season went into early crisis mode on Sunday as a shoddy performance at Brighton brought a 3-2 defeat, with captain Paul Pogba later admitting Mourinho's men lacked "hunger" and that the attitude was not right.
The loss came on the back of a troubled summer, with Mourinho frustrated by the United hierarchy's failure to make signings before the transfer deadline and the Portuguese's warning that a "difficult season" could lie ahead.
There has also been tension between Mourinho and Pogba, the club's most expensive signing, and a high-profile pre-season spat with the France forward Anthony Martial.
Mourinho has been cut to 3/1 with Sky Bet to be the next Premier League manager to leave his post, ahead of Leicester's Claude Puel.
"(Mourinho) is the wrong man for the job," Sharpe said.
"When he came to Chelsea the first time he was quite charming and fun, but now he just seems dour and fed up.
"He's moaned about not signing new players and not bigging up the ones he's got.
"The football's not entertaining and what makes it twice as bad is that their two biggest rivals, Man City and Liverpool, do play exciting football.
"His negative style does not fit in with the expansive football that United fans want. I think he'll be gone before Christmas."
