Manchester City have set an asking price of £30m for Jason Denayer, according to reports.
The 20-year-old has not yet made an appearance for City and joined Galatasaray on loan in August.
A £7.3m move for the defender has reportedly been discussed between the two clubs but Manchester Evening News claims that City value Denayer at £30m.
The Belgian international is believed to be in line to replace 36-year-old defender Martin Demichelis at Manchester City next season.
