I think you misunderstand my view. It's not that I think we are incapable of playing a progressive game, that's obviously not the case. We just saw the previous manager do it. My view is we can't do that whilst playing in a balanced setup. That is something we haven't seen in years, not since Poch. It's either been all defensive all out suicidal attack.
So yes if we play a mid block defensive line, this same squad will struggle to build play from the back because it's lacking in players capable of playing passing football in that area. None of our CMs are passers, not one of them. I remember debating this earlier this season and pointing out why having Romero our CB be our best user of the ball was a problem. Not because I don't want a ball playing CB but because that CB should be a bonus, in addition to the passing quality from the heart of the team ie. the midfield. Now some will say the likes of Bergvall can drive with the ball and sure he can, but he will also lose the ball repeatedly in dangerous spaces as he often does. Is that worth the risk? Maybe for some, but I think in the short as those losses of the ball lead to chances and goals conceded that view would change quite sharply. You don't build successful football from deep via driving, you do it via passing rotation. There's a model to follow when setting up as a progressive possession team, it involves deeper ball players that we do not posses currently.
For me it's the same reason Ange played his line so high, because he knew that to get the short triangular interchange of passes that he wanted he needed the various players to be much closer to each other. That worked in an attacking sense, massively overachieving goal wise re the player quality but with lots of very obvious downsides.
Now we have a coach who has a more sensible line position but who is also struggling with the same issue we've had for years, how to link the defence to the midfield and through to the attack. This isn't a new problem, it seems to me so many have just forgotten because of the period under Ange and even with him we suffered the same issues. I don't see that as a coaching deficiency, that is very clearly a player attributes issue.
So ultimately sure I think Frank could be more ambitious, I wouldn't have made many of the choices he has ie Xavi on the left, Bentancur and Palhinha, but I can't lie and say I think the decisions I would have made in terms of player positions or selections with the available squad would have fared any better. They would be more attacking for sure but also would leave us more exposed, I don't believe we are capable of playing a dominant game as it stands I just don't have that belief that you have.
