Simple Facts will dictate the decision to
1. Sack Jose Mourinho
2. Appoint a New Manager
Finances - United will not want to pay huge compensation to other clubs for their current Managers when they will have to pay Jose between 15M and 20M.
Therefore Zidane is available, a recent winner of CL and was one of the 10 best players to ever play the game. The last being point key to managing the Egos of Martial, Pogba, Lukaku and Lingard.
Even more important to this decision is that Zidane can definitely attract World Class players and young talented players in the January Window. The deciding factor will be that if we carry on with this current toxicity, the Club could have played 21 games in PL by the New Year and have less than 30 points, some 10 to 15 behind 4th place. We could also be out of the CL after losing to Valencia and Juventus, already knocked out of the Caribo Cup with our season depending on a FA Cup 3rd Round game.
Even Woodward is not that much of a fool not to act now why Zidane is available and without compensation!!
