you need the wing backs no matter what
if you used it on previous ones you were very lucky to do well
but the way the formation is to work is two lines of 3 and then two very attacking players bombing down the wings its really kind of like 5 midfield i suppose thoug
but if your adamant to use 3 defenders and no wing backs just have 2 defensive wingers to try and stop supply over them into the spaces behind them it might work
I've had great success playing an incredibly offensive 3-4-3 with ball playing centre backs, anchor man, centre mid support, attacking mid, 2 poachers and a complete forward. however i was playing with man city meaning all my players were incredibly gifted and i'm not sure this tactic works for lower teams
I'm currently trying to recreate Bielsas world cup tactic using 3 Centre defenders and no wingbacks but wide midfielders and currently doing good. it is possiple playing 3 central defenders.
