Fed up of people calling for a managerial change.
The failure is down to one simple reason. The board undermining managers when players are not performing.
The players as a consequence have been allowed to be prima donnas. When they are dropped from the starting line up they whine and moan knowing its the manager who will be going before they do. How else to explain Pogba's message after Mourning was sacked "you messed with the wrong baller".
When Mourinho dropped Pogba from the starting line up mid-way through the 2017/2018 season, Mourinho should have received 100% backing from the board. Instead, it was Mourinho that was undermined and Pogba was brought back to the starting line up. that set the precedence, which was then exacerbated during summer of 2018 transfer window when Mourinho didn't get the players he wanted. Souness on Sky called it at the time.
By comparison, why did SAF have players busting a gut for him? Because they all knew that if their standards fell, or worse if they were to undermine SAF, they would be out the door. They knew that the board (Gill, Charlton) would back SAF 100%. When Stam published that book, SAF saw the danger of him as the boss being undermined. Same with the David Beckham boot saga. Both Stam and Beckham were shipped out ASAP. At the time people questioned the decision, particularly when short term results wavered. But it was absolutely in the long term interests of the club by maintaining 100% respect for SAF.
We've now had 2 of the best managers in history fail at Utd. LVG and Mourinho. Bullsh*t to say either manager was past it. They failed because the players knew they could underperform and it would be the manager and not them facing the boot. Until that situation changes Utd will continue to fail regardless of (a) the money spent on players and (b) regardless of whether adhering to the "united way" fantasy bulls*t.
