Jose Mourinho has claimed, in an interview with the Evening Standard, he has “inside information” that Manchester United are unhappy with their current plight.
But he does not believe manager David Moyes’ job is under threat, even though United are only seventh in the Premier League, 11 points behind leaders Arsenal, and were knocked out of the FA Cup by Swansea.
And Mourinho, whose Chelsea side host United at Stamford Bridge on Sunday, said it is very unlikely the defending champions will retain their title.
Mourinho, a friend of former United manager Sir Alex Ferguson, was tipped by many to succeed the 72-year-old at Old Trafford before Moyes was appointed in May.
The Portuguese said: "My feeling, which is based on years of communicating with Sir Alex and some inside information, is Man United are not happy, but they are calm.
"They trust David. David trusts them. I don't think David is under pressure. The pressure is something virtual. It is something that comes from the media as a consequence of not having the best results.
"The most important thing in all of this is not the pressure that comes from the outside, it's the reality of the inside.”
Mourinho believes Moyes is a long-term appointment and suggested the Glazer family, who own United, will back the manager during a transitional phase.
He added: "The manager is calm and they are thinking this is our manager for the next two, three, four, five years.
"So they're all together and are going to rebuild again a big team. The bad results will finish. They will get back on track, although it is probably too late to win the league because they're too many points behind the leader."
