In business terms unless we see the output of Pogba and his impact in the team, we cannot conclude it as incredibly poor at the moment, but in footballing terms they have improved a key position and that's all that matters. Most of our fanbase don't care about 50m being spend on Stones and try to explain 'IT'S NOT MY/YOUR MONEY'. So why bother with the price tag of Pogba ?
Yep if a club can afford a player and he will improve the team its a good purchase! Bottom line it isn't football fans money.
