FCSB scorer Daniel Birligea has demanded UEFA investigate Dutch ref Serdar Gozubuyuk and claimed he 'supported' Aberdeen' after they threw away a two-goal lead at Pittodrie.
The Dons travel to Romania next week for the second leg of the Europa League play-off after a pulsating 2-2 draw at Pittodrie.
Birligea opened the scoring in the tie, but he was furious when ref Gozubuyuk sent off Juri Cisotti for his lunge on Nicolas Milanovic in the first half.
And he could land in hot water with European football's governing body after his attack on the official.
He fumed: "We hope that UEFA will do an investigation or something, because the referee... I saw from the first minute that he came to support them.
"He told me in the second minute of the game I was talking too much. He showed total arrogance towards us.
"He ruined football. I hope we get a fair referee in the second leg.
"The red card was a mistake.

"I am proud of all the colleagues who gave everything on the pitch.
"We were a man down and had three players who couldn't play because of visa issues, so we have to be happy with a draw."
And Steaua's madcap owner and president, Gica Becali, accused the ref of being on Aberdeen's side too.
He said: "There were two tackles by Aberdeen players that were worse than Cisotti's.
"So the referee was on their side.
"I don't think they can beat us in Bucharest. That's fine. What happened, happened.
"Let's qualify for the Europa League this season, then win the league and get in the Champions League next season."
