The agent of Auxerre defender Willy Boly believes that playing Champions League football could determine his potential move to Celtic.
The 21-year old French centre-half is being linked with a possible £4million move to Parkhead and with a spot in the group stage of Europe's premier club competition up for grabs, his representative Olivier Yenge suggests a deal could be on the cards.
"Champions League football would be very attractive for Willy," said Yenge.
"We know Celtic are interested but we have had no offer yet. However, I expect them to be in touch."
Celtic are on the verge of qualifying for the Champions League as they take a 2-0 away goals lead over Swedish club Helsingborgs heading into tonight's home leg at Celtic Park.
