Speaking of our ability to buy Pogba personally I thinks it’s possible. It will depend on a lot of things, but if United is asking for lets say 100m it wouldn’t necessarily mean we need to pay 100m right now. There are always multiple options and most transfers are paid in multiple installments. We’re paying De Ligt in multiple installments, Higuaín was paid to Napoli in 2 years, we’re still receiving money from Kean, etc.
Its more if the board thinks that the financial impact Pogba would have on us is sustainable when we’re still paying big time for Ronaldo, an improved contract for Dybala, Higuaín still on the books, Khedira, etc etc etc. But we shouldn’t forget that financially we’re a top 10 (ok, 11) club in the world so there is always some room for investments.
So like always actually we’re depending on good results in the CL and we need to have some luck with selling deadwood like Perin, Khedira and the rest.
Honestly I feel that it is possible, if we continue to make some smart deals as with Arthur/Pjanic, Berna/Milik, than I feel optimistic. It would also depends on Pogba willingness to ask for a acceptable salary.
If Paul really wants to come back, with his contract ending in 2021 (if know they have an option for another year, but I’ve been reading multiple times that United won’t use it), we’re in a good position to negotiate. He’s been a pain in the ass for United last years, so somewhere should be the willingness to close that chapter for them aswell.
