Gundogan has joined the Turkish Super Lig champion on a free transfer from City, with the 34 year-old midfielder reportedly signing a two-year deal. 

The former Germany international returned to Pep Guardiola's side last August after spending the 2023-2024 season in LaLiga with Barcelona. 

Gundogan made 54 appearances across all competitions in his second stint at the Etihad Stadium, scoring five goals and registering eight assists. 

"I'm very happy. It's a proud day for me and my family. We're very excited. We're very happy to be here," Gundogan said.

"Hopefully, we'll adapt to the team quickly, meet my teammates and play some fun football.

"There were transfer talks, but I wasn't keen on anything. Talks with Galatasaray started in May or June. There were other issues. They sorted out [Victor] Osimhen and [Leroy] Sane.

"We had to wait a bit, but thankfully, we'll make all the signings on the last day and become part of the Galatasaray family.

"Sane and I are good friends. We play well together. I met with Coach Okan [Buruk] two days ago. After that, everything moved very quickly.

"I'm looking forward to working with him. I'm very happy. It's a very proud day. We've returned home. We're very happy about that.

"It's a great pride to be a part of the Galatasaray community. We've reunited. I'm looking forward to the moment I put on that jersey and step into the stadium." 

Gundogan has become Galatasaray's seventh signing of the summer, and follows compatriot and former City team-mate Leroy Sane to the club, after he joined from Bayern Munich on a free transfer. 

Okan Buruk's side has made a flying start to it 2025-2026 league campaign, winning all four of its matches, including a 3-1 win over Rizespor. 

Gundogan could make his debut on 14 September against Eyupspor, with Galatasaray kicking off its Champions League campaign away to Eintracht Frankfurt four days later.
