FOOTIE chiefs have slapped Celtic with two more charges - one for their fans' behaviour and another for their players' .
The Parkhead club face a Uefa charge relating to supporters letting off fireworks, just a matter of days after being fined for an identical offence.
However, the players have also landed the club in hot water after being accused of "improper conduct" during their 1-0 Europa League defeat by Inter Milan.
Flares were lit in a section of the San Siro, housing around 3000 Hoops fans, on Thursday night.
Hoops boss Ronnie Deila described it as "very disappointing" and said: "We have to get rid of this, this is is nothing to do with football.
"Again the fans were unbelievable, you can hear the fans still singing now, that is important for us but again we have to behave in the right way."
Virgil van Dijk was sent off in the first half for two bookable offences.
Craig Gordon, Adam Matthews, Emilio Izaguirre and Nir Bitton were shown yellow, with Kris Commons also being booked after full-time.
Inter have also been hit with a charge for the "setting off of fireworks"
Celtic had drawn the first-leg of the Europa League last-32 tie 3-3 at Parkhead.
Earlier this week, Deila had pleaded with Parkhead fans to be on their best behaviour for the match.
It came after the Hoops were fined more than £7000 by Uefa for crowd disturbances at Europa League match with Dinamo Zagreb.
European football's governing body held disciplinary proceedings against the Parkhead club and at the outcome of the inquiry, the Parkhead side was sanctioned with a £7,328 fine.
The move followed allegations of "inappropriate behaviour" by travelling fans at the game in Croatia last December.
A red flare was lit at the Celtic end of the stadium during the match.
Celtic fans have been warned before about the use of fireworks and flares.
Chief executive Peter Lawwell has condemned the "small minority" of supporters who were "damaging the reputation" of the club.
The punishment marks the fifth time in just over three years Uefa have taken action against Celtic for a variety of transgressions, including illicit chanting, illicit banners and setting off fireworks.
Celtic were given a £42,000 fine in 2013 after their fans displayed an "illicit" banner at a Champions League match with AC Milan.
The same year, the setting off of fireworks by supporters at a Champions League qualifier with Cliftonville resulted in a fine for the club of slightly more than £4000.
Uefa fined Celtic £21,000 in 2012 after supporters displayed an offensive banner and set off flares during an away game with Udinese.
