Walker, 33, has a contract with the Etihad until the conclusion of the upcoming season, but talks to extend the English defender’s current deal have not yet advanced.
According to sources, Walker is ready to transfer to the Bundesliga to continue his professional career at the highest level after growing impatient with City’s lack of a firm offer to negotiate new terms.
The former Sheffield United right-back, who is also being pursued by Saudi Arabia, was benched for last week’s Champions League final victory over Inter Milan in Istanbul in favor of Manuel Akanji, who was used at full-back by manager Pep Guardiola.
Walker’s long-term chances at City were previously questioned by Guardiola, who claimed in April that Walker, a £45 million acquisition from Tottenham in 2017, was unable to adjust to a new tactical scheme and was instead favored in a five-man defensive formation.
However, despite the fact that Walker reclaimed his spot and excelled in the Champions League semifinal victory over Real Madrid, particularly in his close encounter with winger Vinicius Junior, sources claim that Guardiola is now prepared to plan for the future by offloading Walker and bringing in a replacement.
Jao Cancelo, a defender for Portugal, is also expected to leave City this summer after spending the second half of the previous season on loan at Bayern.
Ilkay Gündogan, a captain whose contract expires at the end of this month, is also in serious jeopardy. The midfielder was on a list of players who can transfer for free that was provided to the Premier League on Friday.
After leading the team to the Premier League, FA Cup, and Champions League championships this season, Gündoan had been mum on his future, with the Germany international linked with moves to Arsenal and Barcelona.
