It's really hard to break down when done well. I've never seen this City side look more toothless than when up against a good 352/532. Seeing Aguero or Jesus toil completely pointlessly against 3 CBs, seeing the half spaces get closed down and wingbacks block our wingers getting around.
It's a horrible thing to watch.
I still don't think Pep has fully figured out how to beat it.Getting PTSD from some games against Wolves over the last few years
It's really quite simple in concept, in defense, you have a 541/5311, which just defends with more numbers and easily transitions on counter attacks.
If you want to pin the opposition back, it has a simple shift of the wide areas pushing up 343 and 352/3511.
And another huge benefit is in it's simplicity of tactics for players.
In a back 4 your fullbacks have to constantly change position when defending or attacking, wingbacks staying wide is much simpler.
Most "wingers" prefer to play in the half space rather than far out wide, and 343 fits this perfectly as well.
A back 3 also let's your CBs push forward and make passes and be creative, which suits most high level CBs.
