It's still 352 people I don't know where you see 433 or 4231.
It's just like Conte's Juve. Score and then drop back too deep just to concede. Buffon fucked it up yeah but I think he didn't see much since 3 players tried to block the shot and none did.
I think they're not as bad as we can see it. The same thing with Juve - the formation limits the squad a lot. Why play age stone 352 when you have SES and Candreva as wingers?
