Odsonne Edouard will only sign a new Celtic contract if there is a release clause inserted in it, Football Insider understands.

The Hoops hierarchy are working to tie down their prize asset to a new deal amid growing interest from Premier League clubs as well as Europe’s elite.

A Celtic source has told Football Insider that the French striker’s camp want a release clause in the deal giving him the freedom to leave if a club pays the fee.

They want a sum that is not prohibitively high for a player the Scottish champions now rate in the £30million bracket.

That puts him ahead of their two record sales, Kieran Tierney (£25million) and Moussa Dembele (£19million), each of whom left in the previous two windows.

There are fears among Celtic supporters that Edouard will be this summer’s latest record departure following his outstanding campaign that makes him favourite to win the Scottish player of the year award.

The runaway league leaders refused to cash in on Edouard during the January window, but the club privately recognise it will be very difficult to fend off advances of the elite in the summer.

Manager Neil Lennon has admitted this week the club has made no progress in contract talks with the front man.

Edouard signed a four-year contract in the summer of 2018 when his initial season-long loan from Paris Saint-Germain was converted into a club-record £9million transfer.

He is attracting strong interest from Lyon and Borussia Dortmund as well as clubs south of the border led by Newcastle United and Everton.

Edouard has scored 26 goals and supplied 18 assists from 44 Celtic appearances in this campaign as well as a remarkable 11 goals in just six France Under-21s matches.

In other Celtic news, it can be REVEALED that the door has opened for the club to sign £40,000-a-week Premier League player after big development.
