Crystal Palace manager Oliver Glasner has admitted the club will sell Marc Guehi this month if a big enough offer arrives.
Guehi is out of contract in the summer and came close to joining Liverpool in September. That move collapsed late on transfer deadline day, when Palace failed to line up a replacement.
Manchester City are now said to be keen, with several European clubs also monitoring the situation ahead of a potential free transfer - including German giants Bayern Munich. Liverpool remain interested after narrowly missing out on the England defender a few months ago.
Pep Guardiola downplayed the likelihood of Man City making a major January signing, but Glasner has been clear that a substantial bid from them, or any other club, could force Palace’s hand.
Glasner said: “There’s the situation that the contract ends in the summer. If somebody is coming, there will be a moment when the club says the financial issue is more important than the sport issue.
“We have to do it and try to get the best. That’s why I’m always saying I don’t know. This is different. There will be a threshold where the club has to say sell.
“If the player says he wants to leave and the money is above the threshold, it will happen.
“I’m not so naive not to know that if a massive offer comes from Man City and Marc wants to do it, it will happen.”
Despite those comments, Glasner has also downplayed the idea that Guehi’s future will be resolved quickly, stressing how unpredictable the transfer window can be.
It comes while the manager himself is also linked with a potential move to Manchester United, after Ruben Amorim was sacked earlier this week.
“Tomorrow starts the next crazy month in football,” he added. “I’ve experienced so many different situations. The next 31 days, everything is possible.
“Everything I say today might be wrong in two days. By the end of the window, most of it will definitely be wrong. That’s why I don’t really care about it and don’t want to talk about it in public.”
