Celtic have been fined €16,000 after supporters let off flares during their Europa League victory over Lazio in Rome.
The Scottish champions were handed the fine following a hearing of UEFA's Control, Ethics and Disciplinary Body.
Lazio were fined €9,250 for their fans setting off fireworks and throwing missiles in the same game, which ended in a 2-1 win for Celtic.
It is the third fine Celtic have received for crowd behaviour this season.
They were fined €12,500 for incidents against AIK in Sweden and €15,000 for banners and chanting in the home tie against Lazio.
Meanwhile, Bayern Munich have received UEFA charges over blocked stairways and an illicit banner following their Champions League encounter against Tottenham in Germany.
Meanwhile, Celtic announced today that 28-year-old defender Nir Bitton had signed a new contract that will keep him at the club until 2023.
Bhoys Neil Lennon sees no reason why a Scottish team cannot reach a European final again.
But Lennon refused to make any bold statement about his team's ambitions this season after they were paired with FC Copenhagen in the last 32 of the Europa League.
Lennon played in the 2003 UEFA Cup final when Celtic lost to Porto, five years before Rangers emulated their progress.
The richest leagues in Europe have since grown even further away from Scotland and many other nations in terms of finances but Lennon believes his club should be striving for the top.
When asked whether a Scottish team could make it to a final again, he said: "Yes. No doubt about it. Why not?
We had great success in the last decade, 2003 and 2008, so I think these things can come round again. I'm hoping it will be us one day."
Lennon, whose side topped their group with a game to spare, added: "We all wanted the Champions League but we have made the most of the Europa League so far. Looking at the squad at the start of this campaign, I felt we could do a little bit of damage in the competition.
"We have done that but there is still a long way to go and a lot of big games ahead. But I am absolutely thrilled with how we negotiated the group."
Cluj counterpart Dan Petrescu tipped Celtic as potential winners of the tournament but Lennon said: "It's too early for that. I would like to make inroads in the competition, it's important for player development, it's important for the club, and it's important for me to develop as a coach as well.
"Europe is always a huge arena to play in. We will try and do our best. Can we get to the quarters and take it from there? That's when you really start to get excited about it but it's too early to say about getting to finals.
"You see the calibre of teams who are still in the tournament, there's a lot of big clubs who will have their eyes on us.
"I don't like making predictions. We don't play until February 20, it's a lifetime in football. So we will see how we are looking and how strong we are, and we may look to bring another couple of players in to what we already have in January."
Like Celtic, Copenhagen dropped out of the Champions League at the third qualifying round. They then finished above Dynamo Kyiv and Lugano to qualify for the last 32 behind Malmo.
While Lennon spoke, they were gearing up for their final game before a two-month winter break. They will resume against Esbjerg on February 14 before the first leg against Celtic six days later.
