This tactic can destroy every opposition,but one thing,you need your team to be like on, defending as one and attack as one,players need to be brothers to achieve this masterpiece!
the current system is 4-2-3-1 with oscar behind diego costa,hazard with inside foward duties with attack duty and william winger,now for matic is complete defensive midelfielder and fabregas as deep lying playmaker,ivanovic is a full back with attack duty and azlipuerta(:S) with support...
hmmm...
i uses this tactic....chielini goes foward and liorente played as centre back...i had 27 shots vs sassuolo and the match came 0-0...then i played with calgiari,i did what have you said,i focused on winger and i lost 2-1...something goes wrong:@
