Celtic could be about to enter a bidding war with Rangers for Dundee striker Nacho Novo.
Nacho Novo scored 25 times last season
BBC Sport understands that Dundee are looking for around £750,000 for the Spaniard, who has also attracted interest from Leicester City.
Dundee described an initial £200,000 Rangers bid as "laughable", with Leicester willing to pay double that.
But Celtic have now made a firm inquiry for Novo and a deal could be done when boss Jim Duffy returns from holiday.
Dundee have quoted a price to Celtic, but the deal is complicated by the player and former club Raith Rovers both due a cut of any fee.
The Tayside club are moving out of administration and insist they are under no pressure to sell the striker who netted 25 times last season.
A spokesman said: "There is no question of us letting a player of that quality go for anything less than his true value.
"We can afford to be robust in our dismissal of unacceptable offers because we have sold 2,200 season tickets.
"That represents £500,000 in hard cash and is a magnificent effort from our fans."
Dundee also rejected a bid of about £500,000 from Crystal Palace for goalkeeper Julian Speroni, saying that there were too many conditions attached to the deal.
Novo arrived at Dens Park for £100,000 from Raith Rovers in 2002, having joined the Kirkcaldy outfit from Spanish lower league side Huesca.
