The 33-year-old, who captained Pep Guardiola’s team to an unprecedented Triple Crown, departed City for Barcelona in 2023.
But the widely reported financial problems of the Catalan giants have kept them from acquiring new player Dani Olmo, and letting go of one of their better earners might expedite that process.
Early personnel concerns for City include the £81 million departure of Argentina forward Julian Alvarez to Atletico Madrid and the potential four-month absence due to an injury sustained by Norwegian winger Oscar Bobb.
Gundogan wouldn’t need a transition time and may offer a temporary solution to these issues.
Pep Guardiola, the manager, was against Gundogan leaving City.
Gundogan made 304 appearances for City after leaving Borussia Dortmund in 2016 for an estimated £20 million, scoring 60 goals.
In his seven years at Etihad Stadium, he won fourteen trophies: two FA Cups, four Carabao Cups, two Community Shields, one Champions League, and five Premier League crowns.
