i'd be fine with chiesa, vlahovic/kean, iling for a run of a few games if shit goes south and we need a change. (we'll obviously keep using 3-5-2 until those rock steady 1-0's keep coming, fml)
problem is the rest. 4-3-3: who's the 3rd cm? mckennie can't pass, miretti is slow and weak. 4-2-3-1: who's the am, miretti who won't/can't track back if played higher? any 4-man backline: who's the rb, the weakest position of the whole squad? at first sight 3-4-3 could look all right and would comfort kostic the best
