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.
Sebastian Larsson is a surprise inclusion in the Sweden squad for the Euro 2008 qualifiers later this month.
Lars Lagerback's side, who currently top Group F with 19 points and also have a game in hand, play Liechtenstein on 13th October before facing Northern Ireland four days later.
Larsson, 22, has earned a call-up for the games after regular Premier League appearances for Birmingham this season.
"He's one of the small number of young players that has managed to establish himself without returning home," Lagerback is quoted on Uefa.com.
Larsson is joined by fellow Premier League-based players Andreas Isaksson, Andreas Granqvist, Olof Mellberg, Freddie Ljungberg and Christian Wilhelmsson.
Internazionale striker Zlatan Ibrahimovic is selected in the 23-man squad despite being suspended for the game against Liechtenstein.
But Kennedy Bakircioglu and Max von Schleebrugge miss out through injury, although Andreas Johansson is included despite a knee problem.
Full squad:
Andreas Isaksson (Manchester City), Rami Shaaban (Fredrikstad); Matias Concha (VfL Bochum), Erik Edman (Rennes), Andreas Granqvist (Wigan), Petter Hansson (Rennes), Daniel Majstorovic (Basel), Olof Mellberg (Aston Villa), Mikael Nilsson (Panathinaikos); Niclas Alexandersson (IFK Gothenburg), Daniel Andersson (Malmo), Andreas Johansson (AaB Aalborg), Kim Kallstrom (Lyon), Sebastian Larsson (Birmingham), Tobias Linderoth (Galatasaray), Fredrik Ljungberg (West Ham), Anders Svensson (Elsborg), Christian Wilhelmsson (Bolton); Marcus Allback (FC Copenhagen), Johan Elmander (Toulouse), Zlatan Ibrahimovic (Inter), Rade Prica (AaB Aalborg), Markus Rosenberg (Werder Bremen)
