The club's coach, Okan Buruk, had a video call with Ederson this week, and there is growing hope that the Brazil international will join Galatasaray by the end of the month.
Galatasaray started the new Super Lig season with a win against Gaziantep, and Ederson seemed to respond to the match result.
During the game, the new Galatasaray player Leroy Sané celebrated the team's victory by posting a photo on Instagram, and among the many likes, he also received one from Ederson, who was his teammate at Manchester City.
