The scouts (read: club) rated Antony at 25m and when Ajax demanded more, we withdraw.
EtH knowing the finances of the club, still insisted on it. Murtough being the muppet he is, decided to go back to that signing. EtH, assuming that he is intelligent, should have known that if you spent 80m+ on him (after spending over 120m on Casemiro and Martinez) will affect our signings next season. He also, assuming that he is intelligent, should have known that after spending 200m the previous season, it probably is not a great idea to spend 100m in luxury signings such as Onana and Mount who do not improve us at all, and then 70m on a kid with 19 goals, when you need to also improve the midfield and attack.
Now, if he is a muppet, like it seems he is, he might now have known that United does not have an unlimited amount of money for transfers. But if Caf knows it, so he should have known. It is pretty basic stuff.
