I see things a bit differently actually.
If I put myself in the shoes of one of the Glazers (and if I shared their values and ambitions), I think I would be looking to remove or eliminate Woodward's perceived influence on the business, purely for PR gains and to protect and grow our revenue.
Whilst Woodward played a key part in the takeover and streamlined our commercial activities, I'd rather take more of a low-key approach when it comes to mugging off our customers, I mean 'fans'. So if they continue to remain disgruntled and create negative publicity for us (which could impact on our revenue streams), I have no problems in removing Woodward from his position and allowing him to take the blame. We've 'spent' £900 million after all, it's not our fault Woodward didn't spend it wisely and keeps hiring the wrong managers. We'll give him a nice payout and he can even do some 'consultancy' work for us in the future here and there if we need him anyway.
I'd then simply replace him with another puppet who will be branded as more of a 'football man', but will ultimately do the exact same job as Woodward.
Ultimately, not much will change, but removing Woodward can make us look good and is another PR exercise to appease the growing discontent in our customers.
