Frenkie de Jong is still not fully recovered... And he is making tons of money which is going up to 25 million euros a year with bonuses. He said that people were wrong and he was actually making much less than that but I don't know.

Isn't it bad to pay this injury-prone player this much money?    I mean he is talented okay but he can't play regularly during a season. The team can't get enough efficiency from him comparing to the money he earns. While Barcelona is trying to raise funds, I think they should consider selling him or cutting his salary seriously.
