And I think you're exaggerating the effects of losing Pogba.
And this is coming from a guy who thought Pogba was the best midfielder in football for the last 2-3 months of this past season.
If we get a couple mids, say Herrera and Matic, or something along those lines, I think this team is improved.
Adding into the starting XI:
Herrera + Matic + Higuain + Alves
makes us better than this season with:
Mandzukic/Morata + Pogba
It's all hypothetical though. We don't know Pogba is leaving. We don't know what mids we would replace him with, and so on. Wait and see is the best option now. Either way, I refuse to meltdown this summer. I did that enough last summer, between losing a CL final, and losing the core of our midfield and attack.
