Crystal Palace have approached Manchester City to sign defender Manuel Akanji.
No official bid has been made, but sources told BBC Sport that Palace have enquired about the availability of the Swiss international.
It is understood City would want about £15m for Akanji, who has not featured in either of their Premier League games this season.
The 30-year-old also has interest from Turkish champions Galatasaray.
Akanji joined City from Borussia Dortmund in 2022 and was part of the Treble-winning side a year later, starting the Champions League final win over Inter Milan.
Earlier this month, boss Pep Guardiola suggested City’s focus was on outgoings having spent more than £150m on six players this summer.
The Spaniard said it was “not healthy” to have so many players in his squad and “people will talk with players and agents to find a solution”.
Goalkeeper Ederson has been heavily linked with a move to Galatasaray, while Tottenham have been in talks to sign winger Savinho.
