From a tactical standpoint I'd argue that things were looking worse, not better, when comfort blankets that are Romero and Vdv were out there playing, as their presence was allowing Ange to be even more cavalier and one dimensional with his pressing schemes, defensive line and such. This obviously doesn't mean their absence has suddenly made Ange a tactically more astute manager, far from it. But things weren't better with Romero and VdV in terms of Xs and Os. They were just really good at papering over the cracks.
Their absence has forced his hand to tone down some stuff, to start look elsewhere for answers. That second half against the Wolves where we almost parked the bus, second leg against Liverpool where we did -try to- park the bus, that pitiful attempt at a back 3 against Everton in the first half were all Ange's attempts at innovation. Of course he failed -miserably- in all of these, as there was very little coherent and sound thinking going on behind these changes. He was just throwing things at the wall to see what sticks. Nothing did unfortunately.
I think at this point even he knows that asking your CBs to stand on the halfway line and do extraordinary defensive work every match is not a viable strategy. You don't see the Gray-Danso duo playing the same way the Romero-VdV duo was playing. He knows things have to change, that he can't bulldoze his way through opponents and competitions. But knowing and doing are worlds apart, and he has been coming to this realization. He just lacks the required tactical acumen at this level, and I think he knows this too.
In that sense I feel for him, as he has been expecting to be put out of his misery for quite some time. Don't let that fake bravado fool you, he's deeply insecure inside. This negligence of Levy and co has been hurting him too. This is not me painting him as some kind of a victim, because he's not. For starters, he can always resign instead of holding out for the payout. But I'm calling it like I see it.
