IMO Lemar would play LM in the 3421 unless Sanchez is sold, and Kolasinac would start as CBL.
Do not like the 4231 unless AW buys a genuine DM type to start ahead of Rambo,
which I don't think AW has any intent in doing.
Don't mind the 433 / 4312 & would prefer this to the 4231.
Disagree that the 442 is the only other option and that we'd be required to sacrifice Ozil.
IMO we'd more likely see a 4222 wirth the same players as seen in the 4312 = Cech; Bellerin - Mustafi - Kos - Kolasinac; Xhaka - Rambo; Lemar - Ozil (with both possibly playing as wide playmakers on the flanks and moving laterally rather than providing width down the flanks); Lacazette - Sanchez (with Sanchez playing from deep).
