A transfer to Manchester City for Gianluigi Donnarumma seems almost certain, but if you look at the Turkish media, they are still saying he will come to Galatasaray. 
Apparently, Manchester City will pay 50 million Euro for Donnarumma. And then they may sell Ederson. Galatasaray could then acquire Ederson. The likelihood of Donnarumma coming to Türkiye was already very low. Why would he go to a league outside the top five when he could join one of the biggest team in the Premier League? It's still too early for him.

PSG wants less than 30 million, and I believe Manchester City can play for that amount. It all rests on Ederson's move to Galatasaray, as Manchester City is asking for more than Galatasaray is willing to provide. Manchester City's new goalkeeper, James Trafford, needs someone to compete with; his performance in the last two games was bad, prompting Manchester City to consider purchasing another goalkeeper.
Signing Donnaruma is the best option for Manchester City. Although Manchester City's problem is not only the custodian, having a good goalkeeper like Donnarumma, who had a great season with PSG last season and won five trophies with them, Ederson's contract is coming to an end soon, so Manchester City should just sell him and stop asking for too much money because they no longer believe in him.
