While that side might look good on paper it's changing the system to something the players weren't familiar with which (arguably) got us in this mess in the first place. 4-4-2 is a must. Stability in all aspects of the first team is a must. No fancy tactics, no chopping and changing, just work on morale and get back to basics.
It's not fancy tactics really though, just putting players in positions where they are suited. No left backs playing right back, no forwards playing wide or anything daft like that. Just removing an ineffective forward and putting Zog central with a free reign. It shouldn't be too hard to implement.
I thought you said not playing players out of position?
