Never. Ever. Ever underestimate how foolish the MUFC board (and management) can be.
In the last 3 years:
1, replaced a Galactico class manager (Fergie) with Moyes and gave him a 6 year contract. Jose (the ideal replacement) was available but, they thought it would be better to hire a manager who has never won a trophy in his life.
2, got rid of our entire (experienced) defensive line, in a single transfer window.
3, bought Fellaini for above his release clause
4, kept faith with Moyes even after he'd basically given up on our entire team and the season. And only sacked him once the season was completely wrecked.
5, bought Di Maria - British Transfer Record. The only player listed in the World FIFA XI, who was playing in the EPL. Arguably Madrid's best player. MOTM in their final game (CL Final). We did not know how/where to play him and sold him within 12 months, for a significant loss.
6, attempted to sell DDG (our best player for many years) - they only failed because of Madrid's mess-up.
7, LVG was allowed to implement his non-goal scoring philosophy, even though the fans/media were getting on his back. He was even booed. The OT fans chanted "attack attack attack". He was eventually sacked, but was given approximately half a season to rectify the boring football which he had implemented...but he failed to change.
I'm sure there other errors in judgement, but it would not shock me if they sold Pogba a few years later for a cut price deal, to our rivals.
