In the entirety of last season he had no plan B when the opposition sat someone on Jorginho as you pointed out, so I’m not holding out hope of him figuring it out now 1 month in.
4312 is his other fav formation and with 7 CMs, Dybala and his vision for Berna, it'd be a good alt formation for us down the line.
But I'm not sure it's a good idea to make the change already when they're still learning 433.
Last weeks it was he is anti rotation, and he surprised a lot of people with too many changes before fixing in 2nd half.
Give the guy a chance. Maybe he isn't as change averse as you think. Turned Sarrismo into almost calcio last season with Chelsea after seeing that's what was needed.
But I hope he "figures out" 4312 later on, not now.
