The trouble is who will he replace in midfield? Wharton 100% no. Kamada, maybe but that would be more of a "like for like". Surely, we need a box to box enforcer to play alongside Wharton? Original Doucore could be the one but who knows if/when he will get back to that. That leaves Hughes and Lerma who I see as mainly being subs to be brought on to shore up a game.
Going to 4,4,2 or 4,5,1 should allow for another creative midfielder. However, that would be a major move away from our trophy winning formula. Though, with our current squad, I think it is certainly something that we should be looking at. I think either set up might also settle and help firm up our back line.
