Davie Hay has told The Glasgow Evening Times that Celtic should wait before pulling the trigger on a permanent deal for striker Odsonne Edouard.
The 19-year-old joined Celtic on a season-long loan from Paris Saint-Germain in the summer and initially looked stuck behind Moussa Dembele and Leigh Griffiths in the pecking order.
But the young French hitman started the Hoops' visit of Motherwell in December and repaid Brendan Rodgers's faith in him by netting a hat-trick.
With Dembele and Griffiths both linked away, the talk this week has been centered around whether Rodgers would sign up Edouard on a permanent deal - for around £7 million, say The Daily Mail.
And athough Hay believes Edouard has the potential, the Celtic legend feels that his former club should wait before spending that type of money - a club-record amount - on a player still relatively unproven in Scotland.
"We have seen flashes of the player but given the current pricetag that he carries of £7m, a fee that would make him Celtic’s most expensive signing, I am not sure that there will be a rush to commit just yet," he told The Glasgow Evening Times.
"I would think that the jury will be out on that one between now and the end of the season.
"You have to bear in mind that what we see of the player is not the same as what the manager sees in day-to-day training. But I do think that the teenager has to still to convince.
"He scored a hat-trick against Motherwell and has shown up reasonably well but I would think that for that kind of money that the player has still to convince."
