Completely agree. Mata is a second striker/goal-scoring attacking midfielder. He's the guy who makes great runs and within a moment or two wins you the game through a goal assist through his touch, movement, intelligence and finishing. Instead we've dediced he's this wide Debruyne/Zidane-esque playmaker who is supposed to be the one breaking the packed defence and dictating play. It's really very strange. So I agree with you on this.
But I think you the impact of managerial changes on our cohesion (below). It's only United fans who treat managerial changes as such a big deal. Yes, the lack of a DOF hurts continuity but we're so well funded, it should offset that to a great extent. Klopp has also had one season at Liverpool and noone would have called them dysfunctional last season and he didn't even spend all that much. Same with Conte last season who didn't even have a season before making them excellent. Yes, you could argue that Moyes and LVG did more damage than those two clubs endured, but we also have spent money on building a very strong team that should not be dysfunctional.
Liverpool haven't had managers with over-burdening philosophies until Klopp (and even he just wants fit, young athletes with pace, stamina and a general level of quality), so although the quality of their players might be less than ours, what they are asked to do isn't particularly hard to implement.
We, on the other hand have gone from:
- someone way out of his depth who disbanded us to a;
- manager who wanted players in with very specific traits to match a very particular philosophy to a;
- manager who, ideally, wants a group of 6ft plus physical specimens who practically all must revolve around pace and/or power.
It's an extremely broad switch back and forth and it leads to a carousel as each many in succession wants to get rid of players from the former manager's tenure who simply don't fit with what they want from a team. If we had a universal manager, the type who works with what's at his disposal and turns them into the best they can be, it wouldn't matter, but when you have managers who practically diametrically oppose each other, there are bound to be massive issues with the squad - and if Jose is shown the door or walks out mid-project, we may see the same carousel continue if we get in another manager with a staunch and specific approach to the personnel he wants at his disposal.
Our budget is neither here nor there, really, and if anything, can prove to be a backfire in itself as you can imagine how reluctant the higher ups might become to constantly pander to each new manager with expensive players coming in to replace the last set of expensive players from the manger preceding.
If we want to avoid this, we need a club philosophy and DoF or to bring in players who are more universally adept rather than specialists who have skill sets that thrive only under certain managers and ways of playing but are then marginally effective players outside of that.
