Representatives for Kris Ajer and Olivier Ntcham have asked Celtic how much they are valued at, according to a report.
Sky Sports say that the valuations have been requested ahead of both men potentially leaving Parkhead this summer. Clubs in England's Premier League and further afield in Europe have been linked with moves for the duo. This week it was reported West Brom were keen on a move for Ajer.
The news comes less than 24-hours after Celtic crashed out of the Champions League after losing to Ferencvaros.
After the match Neil Lennon said he was growing tired of players who didn't want to be at the club, and were clearly trying to engineer a way out.
He said: "There are some players who may want to leave and have made inroads into that over the last six months or so.
"So if they don't want to be here, we have to do something about it.

“If they are making waves to leave the club they are obviously not committed. And I want players who are committed to the club.
“I’m putting it out there because it has been bugging me for a long, long time."
