CELTIC will have to get involved in a bidding war if they continue their pursuit of French teenage wonderboy Herba Guirassy.
The champions have been credited with an interest in the Nantes left-sided winger, but the Ligue 1 side have no intention of allowing their hottest property to leave on the cheap.
Belgian giants Club Brugge tested the club’s resolve with a £4.1million offer for the 18-year-old flanker and were immediately knocked back, according to a report in L’Equipe.

ON THE BALL…Nantes’ teenage ace Herba Guirassy.
They are ready to add £200,000 to that figure over the weekend, but it is believed that will meet the same fate as the initial bid.
Brendan Rodgers is also looking at Royal Antwerp’s £5million-rated raider Michel-Ange Balikwisha, who also operates on the left, as CQN reported earlier today.
The Hoops boss is looking to strengthen this area of the team with doubts over the futures of Honduran Luis Palma and Australian Marco Tilio who both spent periods on loan last season to Olympiakos and Melbourne City respectively.
Guirassy hit the headlines with a series of impressive displays in his breakthrough season with two goals in 19 league appearances.
