I think @Adnan is making a crucial distinction that's getting lost here. This isn't about whether ETH executed well (he clearly failed in many ways), it's about whether he was set up to succeed in the first place. Both things can be true: ETH failed as a coach AND recruitment failed to give him the tools to implement what modern football requires.
@criticalanalysis you're right that concepts mean nothing without execution. But Adnan's point is that execution becomes nearly impossible when you don't have the right profiles. You mention Flick or RDZ would instantly implement higher lines. Maybe they would, but look at what Flick inherited at Barcelona: defenders who can pass (Koundé, Cubarsí, Eric García), midfielders who can receive under pressure (Pedri, De Jong). He didn't have to coach those abilities into existence, the profiles were already there.
On McTominay, Adnan isn't saying using him as a battering ram was ideal football. He's saying given the constraints (CBs who couldn't/wouldn't step up, midfielders who couldn't progress play under pressure), ETH adapted by using McTominay's strengths higher up while bypassing the broken build-up phase. That's just pragmatism given bad recruitment, not really some tactical masterstroke.
If I understood your points correctly:
- criticalanalysis: ETH had enough to work with and failed to implement anything coherent for 1.5 years
- Adnan: ETH tried to implement a modern system but lacked the foundational profiles, so it collapsed
I tend to agree with Adnan here, because our inability to play coherent modern football for the last 12 years goes well beyond any single manager. It's an issue that's plagued everyone post-Fergie: can't progress the ball under pressure, can't defend transitions in a higher line, midfield gets bypassed. That pattern suggests the issue runs deeper than one manager's incompetence.
And look at what Wilcox spent £200m+ on. Three attackers. If the plan was to implement modern, proactive football, why weren't those funds directed at the spine? We need to prioritize the foundation first. We did the opposite, again, under a "new structure" that was supposed to learn from past mistakes. You're not wrong about ETH's failures in execution. But the broader point about recruitment determining whether any system can function feels more fundamental. We can keep cycling managers, but until the spine is sorted, we'll keep seeing versions of the same dysfunction.
