Look even if we sign Mbappe, Sancho and Neymar on deadline day, this remains a bad deal with United. 10m deal on agent fees + a 200k a week for a 33 year old striker is stupid, especially since its spent on someone who can't even cut it in the French league anymore and whom no one want.
It's evident that your mind is set defending this prats which is strange considering their long history of incompetence.
The only way this deal MIGHT make some sort of sense is that we're signing him and Pellestri. They are both Uruguayans and Cavani might help the latter to settle down. Its still silly money though.
