Aberdeen are facing a hefty fine from UEFA after two supporters set off flares shortly before their Europa League match at Sigma Olomouc. The Dons were docked 10,000 euros two years ago after a supporter ignited a flare during a UEFA Cup game against FC Dnipro in Ukraine.

Aberdeen confirmed on Saturday UEFA's match delegate had included the flare incidents in his report.

The club have appealed for supporters to identify the culprits and have posted pictures of the pair on their official website.

Operations manager John Morgan said: "Despite the disappointing outcome of the tie, most of our fans thoroughly enjoyed the trip to Olomouc.

"However, the setting off of flares is something we have repeatedly warned supporters about as, quite rightly, UEFA will simply not tolerate it.

"Consequently, we are looking for our fans to help us here in identifying those responsible in order that we can take the appropriate action.

"Once again, though, I would reiterate that our supporters, in the main, were a credit to the club and Scotland and it is only that small element that seems intent on spoiling our good name."
