Just my personal opinion, but I think the reasons for AVB's sacking were self-evident enough to not require explanation.
It’s not just the three hammerings that we’d taken in as many months or the fact that we’d won two out of seven games following the Liverpool disaster; it’s the fact that our tactics, the level of harmony and understanding between the players, and basically our sense of team spirit was in total disarray.
AVB was brought in as a ‘project’ manager and yet it didn’t even look like he had the foundations of a project down after an 18 month stint at the helm. To add to that, the fact that he couldn’t make it work with basically any of the new players he was given, and that he was in fact willing to publicly complain about not getting the totally unrealistic signings he’d wanted, indicates he was far from pragmatic or consensual enough to work with Levy for any long stretch of time either.
AVB was brought in to be the ‘long term’ guy, and IMO he’d demonstrated fairly clearly by last weekend that he wasn’t going to meet that brief. No progress, no level of trust or mutual respect with the chairman, constant standoffs with the media and a hint of biting the hand that fed him starting to creep into his press attitude as well. This was evidently never going to work out over time.
