The midfielder has returned to the Premier League champions on a one-year contract after his departure from Barcelona.

Gundogan won 14 trophies and made 304 appearances during a successful first spell at City before departing for Barca in the summer of 2023.

The player impressed during his first season at Barca but they have opted to get him off the wage bill so they can register new signing Dani Olmo while complying with La Liga spending rules.

Gundogan said: "My seven years at Manchester City were a time of pure contentment for me, both on and off the pitch.

"I grew as a person and a player, developed a special relationship with the City fans and enjoyed amazing success. It was an exceptional period in my life.

"To have the opportunity to return here means so much. Everyone knows the respect I have for Pep [Guardiola] – he is the best manager in the world and working with him every day makes you a better player. You feel constantly challenged, which for any professional is exactly what you want. I cannot wait to work with him again."

He also wrote on Instagram relating to his Barca exit: "I am leaving in a difficult situation, but if my departure can help the club financially, it makes me a bit less sad."

City manager Pep Guardiola revealed that the chance to sign Gundogan again came as a complete surprise.

The coach said: "It was a complete surprise, unexpected.

"We didn't have any doubts when the possibility to re-sign him was open, and we're absolutely delighted that he's back."
