I disagree, they should have asked for more. At least 70+10 not 60+8+2m. Hakimi is insane and he is 22 y/o. Most of the merda fans arent happy with the transfer fee too. They paid 45m for him and are getting 60m at the moment + bonuses. That profit = Hakan's wage for the next 3 years (15m). I know that fee isnt making any difference for them since that cash isnt going to other transfers but still.
But then again it is Beppe and PSG knew they had to sell.
