Aberdeen have appealed to fans who travelled to Ukraine with them last week to help identify the supporter who has landed them in trouble with UEFA.
The Dons are likely to face a sizeable fine after a flare was set off by one of their followers during their game with Dnipro.
Now Pittodrie chiefs want the person named and shamed - and banned from their games for life.
Operations manager John Morgan said: "We must track down this idiot and stop the club's reputation being damaged any further. Ukrainian officials praised the behaviour of the 500 Dons fans who were at the game but we've all been let down by the actions of one person."
Italian club Lazio were fined £5000 and Romania's Dinamo Bucharest £4000 after fans set off flares before their a Champions Leagueclash in Rome in August.
Both clubs were warned any repeat could lead to their grounds being closed and a ban on fans attending games abroad. The Dons' fate will be decided next month.
Meanwhile, Panathinaikos hitman Dimitris Salpingidis is ready to call on Hearts defender Christos Karipidis to help the Greeks in their UEFA Cup clash against the Pittodrie side.
The striker will ask his countryman, a former team-mate at PAOK Salonika, for a dossier on the Dons who make up Group B along with Atletico Madrid, Lokomotiv Moscow and Copenhagen.
Jimmy Calderwood's take on the Greeks in Athens in the group opener on October 25.
The 26-year-old Salpingidis reckons the draw has been kind because they play the Dons at home - and expects to take all three points.
He said: "I will contact Christos to find out about Aberdeen. We also have Takis Fyssas, who was at Hearts, in our squad so their knowledge will be useful to us. The draw is very good for us regarding the fact three teams will go into the next stage. In front of our home fans I am confident we can win."
Panathinaikos are fourth in the Greek League after four games and trail early leaders AEK Athens by five points.
Midfielder Alexandros Tziolis admits there will be no excuses should they fail to reach the UEFA Cup knockout stages.
However, having learned of how Aberdeen disposed of Dnipro in Ukraine in the first round proper he insists the Greeks will not underestimate them.
He rates Spanish cracks Atletico Madrid as the strongest side in the group but feels his side's European know-how could be vital.
He said "The Spaniards are strong but all the teams can cause problems, especially Aberdeen. But we are an experienced team and that will help us."

Tottenham have missed out on a top seeding for Tuesday's Uefa Cup group stage draw in Switzerland.
Spurs were rated ninth in Uefa's seedings and join Bolton in pool two, while Everton are in the third tier with Aberdeen in the bottom eight.
This means they could face a top seed such as Villarreal or Bayern Munich.
The 40 clubs will be drawn into eight groups of five, with each playing two home and away matches. Clubs from the same country cannot be paired together.
The top three in each of the groups will join the teams finishing third in the Champions League groups for the knockout rounds, which start with 32 sides.
Jimmy Calderwood is determined to keep Aberdeen's UEFA Cup run going after putting so much into getting the club back on to the European stage.
The Dons face Dnipro in Ukraine on Thursday night in the second leg of their first-round clash just over three years after Calderwood took over.
The Pittodrie club had finished in the bottom half of the Scottish Premier League in the two years before his arrival but he has guided them to a top-six finish in each season in charge.
The improvement continued last season when Aberdeen finished in third spot and sealed their first European place for five years.
And Calderwood is desperate to ensure the campaign lasts beyond the first hurdle.
After a goalless draw at Pittodrie, Aberdeen would go through with a score draw.
"It will be a very difficult game, they are a good team with lots of quality but we will give it our best shot," said Calderwood.
"We are in a position we have worked so hard for for three years to get there and we are going to work very hard to try and keep it going."
Dnipro started the season brilliantly but have lost their last three games, including a cup defeat by Dynamo Kiev.
They also lost seven goals in losses to league leaders Shakhtar Donetsk and struggling Arsenal Kiev to fall nine points adrift of Shakhtar in second place.
But Calderwood is not reading much into their slump in form and expects Dnipro boss Oleg Protasov to raise their spirits ahead of the clash.
"I have seen the game against Shakhtar and I thought the first half they played really, really well," he said.
"Shakhtar upped the pace in the second half and it was a wonderful performance. It was a wonderful game to watch with lots of pace and a lot of good football. They played a weakened team in the cup tie. Sometimes managers do that and it doesn't work out. Obviously it's not good for confidence but when we played Dnipro in Aberdeen we were poor also beforehand and that was our best performance of the season. With the players they have got and a very shrewd coach, I'm sure we are going to have a very difficult game."
The Dons are without the injured Jackie McNamara, while young goalkeeper Greg Kelly will sit on the bench after Derek Soutar suffered a toe injury.
But every other first-team player travelled and trained as normal last night.
"We had a little doubt about Jamie Smith. He had the flu but he is okay," Calderwood added.

Gretna manager Davie Irons bemoaned his side's dreadful start at Aberdeen as the Black and Whites slumped to their sixth defeat in eight matches so far this season.
Irons' side were two goals behind after only 18 minutes at Pittodrie and, despite an improved showing after the interval, were unable to get back into the match.
Irons said: "We can't keep giving teams a two-goal start as there's then no way back. To be fair I thought Aberdeen did really well during the opening 20 minutes, but the disappointing thing was that we didn't get to grips with the game or compete well enough during that period. We didn't earn the right to take anything out of this game based on our first-half performance."
