I have to agree with the calls to go 4-4-2 we have a very new squad that might eventually adapt to playing a back 5 but it will be too late by then. Just looking at the current squad it looks far more suited to 4-4-2
Most teams play a three in midfield, so with 4-4-2 you can get exposed in the middle of the park.
Bungle's formation from yesterday would be a good option 4-2-3-1 - two deeper midfielders with an attacking midfielder and two wider players supporting the striker.
