A report in The Mirror on Saturday (AEST) claimed Mourinho would be sacked regardless of his side's result against Newcastle United at Old Trafford, a game which it won 3-2 after trailing 2-0.

United dismissed the rumour as "nonsense", but there remains significant scrutiny on the manager's position after a run of four games without a victory in all competitions.

Prior to the win over Newcastle, Neville had his own thoughts on the rumours, and didn't hold back in his criticism of the running of the club.

Speaking on Sky Sports in the UK, he blasted the club's operators in a furious outburst.

"I hope [the report] is not true, but if it is true, I think it's an absolute disgrace," he fumed after also referring to the dismissals of former managers David Moyes and Louis van Gaal.

"This has been going on for five  or six years, now ... Any manager would struggle in that football club the way in which the recruitment is handled, the way it operates. Enough's enough for me.

"Something has to change, and it isn't the manager. It's above that."

He added: "This is the fourth manager in six years. You have to start looking at the people who are appointing the managers, the people who are bringing in the players, the people who are sanctioning the deals, the people who are over-spending on players, the people who are allowing the tail to wag the dog. The dressing room is leading what's happening. The tail is wagging the dog at the football club.

"Get some control back, get some leadership. At this moment in time, I'm furious."

Neville took aim at the club's pre-season statements regarding new recruits, especially in the centre back positions. 

"Who is qualified in that football club to be able to tell Jose Mourinho that [Toby] Alderweireld or [Harry] Maguire or [Jerome] Boateng are not better than the centre backs they've got?"

"There is something rotten to the core with the decisions that have been made over the past four or five years and it has to be coming from the top," he added.

"The people in the boardroom overseeing the operation of the football club are nowhere near good enough. They're not qualified. They're playing football manager with the biggest football club in the world. Stop it. Put people in there who are qualified "
