I think a massive weakness in Chigyy team is that there's absolutely no variation. His CDM are quite similar, they offer the same thing.
The two wingers/wide AM's both have similar playing styles.
Pogba is played out of position, yes he goes forward a lot but that's because he's a box to box midfielder, sticking him up there doesn't really work. He's probably played AM a dozen times in his career. Edit: Pogba has played CAM a dozen + 1 times (Opta)
Griezmann as the sole striker doesn't offer much either, he needs a big man with him, everyone knows that. There's no aerial threat, the only option Chigyy's forwards have is to play low crosses or try to penetrate the back 5. It's too limited. Needed a better variety of players.
