Donnarumma is no longer PSG's goalkeeper: yesterday he wasn't even on the bench and after the match he went on the pitch and said goodbye to the fans so it's pretty clear that he won't be playing anymore for them.
And considering City's loss and the bad performance from their goalkeeper I'm pretty sure Donnarumma will join City before the end of the transfer window.
What I wonder is why PSG are making it so obvious that they don't want Donnaruma anymore? It makes sure that the transfer fee decreases and interested teams would pay less and they have a better negotiating position now.
Somehow not so cleverly done by PSG but yes I also believe that City will get one of the best goalkeepers at a favorable price.
