People seem to be missing the real problem here.
Unless we can learn to play something resembling possession football, all formations based on a narrow midfield and attacking full backs are doomed to failure.
People need to be patient and allow Ferrara the chance to improve our passing game, before looking to make too much by way of adjustments.
Right now, we are playing in a style that is suited to an orthodox 4-4-2 with a squad that is suited to 4-3-1-2.
This means you either work on the team's passing and movement or you force someone to play out of position and switch to a 4-4-2.
The first option is clearly preferable.
4-2-3-1 could work as a temporary solution, but it is not workable on a longer term basis with the players currently available.
