There's no place here for reasoned, considered responses. If that's the formation he wants to play long term then he should play it right now, no matter how unsuitable he deems it to be at the moment. We don't want plans, we just want change. Any sort of change.Maybe he feels he can't move to that system now because of problems elsewhere? Lacking pace in central defence so he feels the need for two defensive midfield shields, or issues with current full backs so he can't rely on overlapping and covering?
