No it doesn’t. Pogba is that good a player that he can play anywhere but he’s a central midfielder.
It's not too different from an LCM role in a midfield 3. Like he said in that tweet, he's wide in defensive phases, but has freedom to float wherever while we're in possession. He literally said he's in a "kind of number 8 position". Different to an LCM in a 433, of course
With Pogba on the left, it isn't too different from a diamond shape at times. Actually, more of a 4222 with McFred, I guess. FBs push up, letting Pogba float in further infield so, depending on who's further forward between him and Bruno at the time (looks like they alternate), he kind of is in an LCM role. From what I've seen, it's something like this:
--------------------------Cavani----------Greenwood
----------Pogba----------Bruno
Shaw------------Fred----------Scott-----------AWB
----------------Maguire--------Lindelof
You can see how, if we get a DM that can do the job of Fred + Scott (if it exists), we could potentially transition into a 433 from this.
