Let me try to rephrase my point, maybe that will clear up misunderstandings and/or clarify where we disagree.
The problem isn't numbers (apart from a couple of positions as you say). And it isn't how "good" the players are (apart from a couple of positions perhaps and lacking one or two "elite" players).
We lack balance imo, particularly when we're missing a handful of key players.
Defensively the difference with and without our first choice back 4/5 is massive. A need for better depth. We'll see if Kinsky and Danso help sort that out, I think so, but still a bit short.
We struggled with ball progression. The "solution" was putting Kulusevski (and then Bergvall) in alongside Maddison. Making an already attacking and ambitious team even more attacking and also vulnerable defensively.
Imo we have quality ball progression from Romero, Porro, Maddison. Could add Spence to that. Bergvall, but young and inconsistent. That's not enough. That's too vulnerable.
Add to that having quite a few wide players that need specific forms of service, players that lack creativity. That ups the need for really good ball progression and creativity deeper, which we way too often miss.
Those were big issues in our defensive problems too. Attacks breaking down and getting countered on, not being able to sustain pressure against good teams, not being able to play through pressure losing the ball in the process (counters, and sustained pressure against us).
If we want to play ambitious football we need more players with more ball playing quality, ball progression and creativity. In the squad. With everyone fit we're fine, a bit short. But takes to little to make us far from fine and that point an ambitious style will struggle.
Again, not sure I agree, I think you are not acknowledging where the flaw is the players vs. system.
- Difference between or first choice back line and not, the reason is our system is so fudging bad, it literally requires the fastest footballer in Europe to cover the cracks. While I agree pre Danso, having Gray/Davies in there is not ideal, the way bigger issue is a combined high line with overcommitted FBs that is easily countered by a diagonal ball over the top. My argument is, Romero would be even better if he was in system that didn't have him constantly running back, Danso and VDV similar (you could probably use VDV to progress ball more into space in a "normal" system), and Dragusin (jury is out) would be decent enough cover.
- Ball progression is 100% a system problem, because the philosophy is stay high to create overloads, we are 2-3-5 in possession, that when the opponent sits in mid block just creates too much congested spaces, which seems to suggest you need an elite level player to get through, maybe just don't fudging over congest the area? (pass the ball, pull them apart)
- Defensive problems mentioned in my first point, you can't play a high line, plus overcommit FB's (and the resulting wide open space behind them), plus have 7-8 players so high that a single ball over/through puts them out of the game. The rest of the point re not being able to manage pressure, this is game management, perhaps the second biggest flaw of Ange's system, there is no compensation for momentum, there is no acknowledgment of "ok, opponent has a bit of control of ball, lets sit for 5-10 minutes, lets ride it out until we get back control, lets not concede"
- Every side in the world can improve, the question is when you say "ambitious football" is that getting us 6th in league or 2nd? because I'd argue this side is good enough for 6th
The single biggest problem Ange system has (and I genuinely think this is part of the design) is it isn't built for individuals (and I really don't see how you fix that), let me explain.
- The core of the system is by being high up the field in numbers, with player fluidity (FB can end up in center of opposition box), you create overloads, you create runners that are fundamentally harder to track (PL teams have countered by marking 1:1)
- What it doesn't do is create isolations, i.e. situations where players are 1:1
What that means is the system is actually ok when you have a set of hard workers, average talent players (Aus/Japan/Celtic?), it doesn't allow you to exploit the talent gap between your team and the dross (Ipswich, Leicester, Tamsworth). It's why we have struggled against brick teams, because the system doesn't let you put your better players against the opposition lesser players in a situation where they can make it count.
Contrast to EL (Frankfurt/Glimt), we played 4-2-4, and all of a sudden, you saw Richi/Solanke bullying defenders, you saw much more comfortable Romero/VDV facing attackers and just blocking them out the game, you saw Porro able to ping in crosses, because the system actually gave better players the chance to shine.
