Looking behind us,4-4-2 is part of us,even then i remember people moaning about 4-4-2,calling it outdated etc. Today people having a go at 3-5-2,for them thats the reason why we look poor.
Formation is just that,a formation,it is not a way of play.Liverpool recently changed to 3-4-3,where they have good movement in those 3 up top,guess some might say that they look better with 3 at the back.I believe that we have some players with poor IQ when it comes to football,also they need way more time to adapt,change their patterns,to learn.
I doubt LvG thinks by watching us that we look great on the pitch with 3-5-2 but then again maybe he believes that no one is that stupid not to get it at the end.
