There’s nothing wrong with your formation, but you have a lot of tweaking to do.
First of all, a lot of your players don’t play on their natural position. That’s never a good thing.
You can get away with a few players that play on some more or less familiar position, but look at your formation, look at your midfield, NOT ONE player plays on a position he’s actually familiar with, some player are even totally unfamiliar with their role (Poulsen, IIsanker, Laimer). Needless to say, that’s not the way to go.
I would advise you to look at the players you have, before picking your tactic, and not the other way around. Having a good looking tactic is nice, but you have to have the right players for it.
Second of all, this tactic is not well balanced at all.
You play a ‘Standard’ mentality, yet you have 5 players with an attacking duty, including your both full backs. On top of that, you ask your full backs to overlap in your team instructions. Which mean that they will be focussed on attacking and overlapping your midfielders a lot. So when you are playing away from home (you mentioned that was a problem), there will be a lot of space to exploit for the opposition behind your fullbacks.
Your team shape also doesn’t match with your team instructions.
A fluid shape means you give your players more creative freedom. Your players will stick to their positions less, but act more as a dynamic unit. In other words, your defender will not only defend, your attacker will not only attack, it’s more of a dynamic and unpredictable unit, something like that. But then, in your team instructions, you ask your players to ‘stick to positions’... do you see the contradiction there?
I don’t really understand the logic behind your team instructions, either.
You want to exploit your flanks with overlaps, but you ask your players to play much narrower?
You play with a fluid team shape, yet you ask your players to stick to their positions?
You want to close down much more, prevent short GK distribution, you have 5 players on attacking duty, yet you want your team to lower the tempo?
I just don’t get what the goal of the tactic is.
Basically, there seems to be a lot of things that make this (at first glance good looking formation) an unbalanced tactic for the team you manage.
Like I said before, look at your players first. And then choose a formation that suits them. And then choose team instructions that suit your formation. And then choose individual instructions that suit your players and the team instructions. And so on.
Good luck with the tweaking!
