As the Imps' search for a striker continues, Deehan is confident a decision will be made on the Frenchman shortly, after the 19-year old was last night locked in talks over his future with the Scottish giants.
The striker has spent the first-half of the season on-loan at local rivals Boston United, who have themselves expressed an interest in securing the youngster's signature.
Director of Football, Deehan is, however, hopeful of beating the Pilgrims to the youngster's signature.
"We're certainly interested in the player, but whether we can take it any further depends on Rangers – he's their player" said Deehan, speaking to the Lincolnshire Echo this morning.
"Dany has impressed in the two games he has played against us this season" continued Deehan.
Pilgrims manager Steve Evans has said that he is keen keep the striker, who has scored five times in fifteen starts this campaign.
"I've held talks with Walter Smith about Dany, but I doubt we'll be able to keep him, either permanently or on-loan" lamented Evans.
"Because of our financial problems we would only be able to afford about 30 per cent of his wages.
