He ask for a pay rise I think he's not mistaking actually, like the guy has really done a lot for that club, sometimes it baffles me on how players will try to do their best for a team but at the end the team will not acknowledge it, I think some team are just fortunate when it comes to loyalty while some are unfortunate in same case, I think in Manchester United there are players whom is actually earning huge wages but doing nothing, but the club still keeps them, unlike Donnaruma who has given his best to the Paris Saint Germain team, but getting declined for a pay rise, hmm it's really mind blowing.
That is when the team and player relations reach to a level that can't be recovered, and that's where they are right now. Donnaruma has every right to be better, and can do greatly, but they are not dealing with anything great, so we should not be considering this. This should be something that will take a while, but it is not that easy to fix.
We should realize that it is not that bad, it's actually quite easy for these relations to be broken, but PSG has to realize, he did ask for a fair increase considering he was the goalkeeper that won all these titles with them, they now got a new one and they are seeing how that's not the same thing. In any case, there isn't that much time left, so I am guessing he might be forced to stay unless they find him a team.
