Dundee midfielder Charlie Adam claims Celtic will get just £5million if they sell Odsonne Edouard this summer.
The striker has been one of the club's star men in recent seasons, but is out of contract in the summer of 2022.
Edouard is wanted by EPL side Brighton, with Serie A giants Roma also said to be keeping tabs on him.
Celtic would demand a hefty fee to sell the Frenchman, but Adam insists the former Paris Saint-Germain youth's value has fallen through the floor.
And he claims Ange Postecoglou would only see around £5m added to his transfer kitty if Edouard does leave.
Adam said on PLZ Soccer : "What are they going to get for him now?
"His performances since he's come back, they're not going to warrant double figures.
"So what do they get? £5m and go from there?"
Edouard has hit 75 goals in 144 games for Celtic across all competitions, winning three league titles in the process.
He arrived for a club record fee from PSG in the summer of 2018, with the Ligue 1 giants holding a significant sell-on clause.
