in 4312 when we push both lichtsteiner and evra up to provide the width we lack, we just leave a lot of space exposed at the back. this allows the other opposition to counter-attack the hell out of us. a more balanced team would consist of 2 wingers that are hardworking as well as being agressive and 1 striker upfront like in a 433 or 4231. however if we revert back to 352 then we know we lack that attacking edge that we need but of course we will be more sure at the back. if we were to make 4312 permanent then we must make sure the fullbacks don't attack as much and also that out AM can make us for the lack of width. When milan had kaka inzaghi and shevchenko they all rotatated and caused the defence trouble. however when we have vidal (who drops back), llorente who just holds up the ball we are not going to get anywhere. We need a mobile striker like falcao and a creative attacking midfielder who likes to run like isco or firmino.
