Marc Guehi joined Crystal Palace from Chelsea in 2021
Crystal Palace manager Oliver Glasner says the club would sell captain Marc Guehi this month if his asking price is met.
The England defender is out of contract in the summer and Manchester City have emerged as contenders to sign him during the January transfer window.
Palace blocked a proposed £35m move to Liverpool last summer but risk losing the 25-year-old for nothing at the end of the season.
City's interest in Guehi has progressed following injuries to defenders Josko Gvardiol and Ruben Dias during Sunday's draw against Chelsea.
