Madrid paid that for Bale
I think theres even more to pogbas price than just his true value as a player. IMO theres also the bragging rights of saying "look at us! We got pogba! Come here to see our new toy“.. factor.
Pretty much like florentino does, o ther mega rich clubs would like to brag about their spending power and the superb player they are buying. So in case Juve start accepting bids for real, im pretty sure one or 2 teams will buckle and go all out in a bidding war around more than 100 mils.
Pogba is THE hot property right anow around europe, and the teams which buys him, will enjoy a superb player for many years, not an expensive flop.
