PSG itself who has been making mbappe's price becomes non sense price. If PSG would not sign him for about €180m and i do believe if PSG will not be able to sell him with such price. The fact that if PSG was crazily buying player with non sense price was greatly affecting the price of player in the market. All of teams were trying to increase the price of their players as high as possible to make sure the big club will pay more for their players. PSG has been destroying the market since the club was buying mbappe and neymar with non sense price. I can't describe it now but all of prices in the market don't make sense right now. Even rice priced €120 which is so crazy for me to see him.
PSG bought Mbappe with a cheaper cost than Neymar and it is true to say they are a club which broke transfer ceiling of the market a few years ago with a crazy transfer of Neymar from Barcelona. No club from any league broke that all time record but the Neymar transfer did changed the transfer market and we have been witnessing crazy transfer prices for some average players like Maguire, Joao Felix, Mudryk. Recent months, clubs from Saudi Arabia made many unbelievable salary offers to European star players. I don't think their clubs will break all time record of player transfer because super star players like Mbappe will not join Saudi Professional League when they are young.
His performance was average but the small club is now also trying to grab money as much as possible. It looks so crazy how the price of football is going up so high like there was no limitation for that.
Mbappe did have better contributions for PSG than Neymar if we compares their transfer costs. However if it is about their salary, Mbappe should contribute more to deserve a very high salary he is receiving from PSG.
