First of all, this is outdated data, right? After all, Mbappe is definitely not in 7th place right now. Also, this is official data, but everyone knows that some clubs (such as City and PSG) are engaged in fraud and pay players extra money through front companies "for consulting services" and "advertising contracts". If we take into account this shadow side of the market, then the situation with wage inflation will be even more clearly visible.
As far as I've heard Mbappe's wages are the most now. However, I have not seen any official news regarding this yet. However, the interesting thing is that none of the 7 players mentioned in the list, except Mbappe, any player on this list did play well in last season. Since the clubs are paying them high wages, the club naturally expects a lot from them. But the players have completely failed to meet expectations.
Officially, his salary is 57 million a year after taxes. Plus bonuses that in three years bring this earnings to 300 million, though I can’t understand with or without salary - but in any case, this is a cosmic amount.
As for the performance of the players, this is a good observation, but I would say that only Bale, Hazard and Grinzman clearly failed, the rest more or less worked their salaries. Someone is better, someone is worse, but at a decent level.
