Celtic boss Ronny Deila has said that he hopes any UEFA disciplinary action taken against the club will not have an impact on fans who plan to travel to see them take on Inter Milan in the Europa League.
The club's following could potentially be in hot water, with UEFA's control, ethics and disciplinary body preparing to look into allegations of crowd disturbances during their recent defeat to Dinamo Zagreb.
"That would be a big setback for us," said Deila, according to Sky Sports News.
"Hopefully we get as many Celtic fans as possible to the game in Italy because that's important for us."
UEFA are due to explore the incident with a hearing on February 19, which is the same day Celtic welcome Inter for the home leg of their first knockout fixture of the tournament.
