Erik ten Hag is under mounting pressure at Old Trafford amid a disastrous second season as manager and the upcoming upheaval of the club’s sporting structure.
Ratcliffe’s £1.3billion deal hands him a 29 per cent stake in United and gives INEOS total control of football operations.
It leaves new United chief executive Omar Berrada and INEOS’ impending other appointments in the coming months with the power to decide Ten Hag’s future.
And as the Red Devils continue to struggle, managers could be throwing their hats in the ring in anticipation of a change in the Old Trafford dugout this summer.
Mourinho is reportedly one of them. The 61-year-old is claimed to have made it his mission to enter a second stint, believing he has unfinished business.
United dismissed Mourinho in December 2018 after a string of underwhelming results intensified pressure sparked by feuds with the club’s hierarchy and his players.
Shaw was one of those regularly criticised by the former Chelsea and Tottenham Hotspur boss, with his weight and in-game intelligence among the subjects raised publicly.
In 2018, Ratcliffe, a lifelong United supporter, disapproved of Mourinho’s antics compared to Liverpool’s Jurgen Klopp, Manchester City’s Pep Guardiola and then-Spurs head coach Mauricio Pochettino.
The INEOS founder pointed out Mourinho’s treatment of Shaw, claiming he had “destroyed” the left-back during his tenure.
He said: “If you’ve got the six teams competing at the top of the table – this is last season anyway – you’ve got three who are managed by glass-half-full guys, [Jurgen] Klopp, [Pep] Guardiola and [Mauricio] Pochettino.
“They get their teams up and energised. And then you look at Mourinho. He’s so down. He destroyed Luke Shaw last season.
