"We get the report and maybe look at video evidence and then they can take actions against specific players."
Chelsea captain John Terry defended Drogba's reaction and said: "I am 100 per cent fully behind Didier for the way he reacted.
"The man wants to win. You could see the passion he played with in the game and the passion he played with afterwards."
In 2005, Drogba was involved in a refereeing controversy against the same side in the Champions League, which led to official Anders Frisk quitting the game. He was sent off for an innocuous-looking challenge on goalkeeper Victor Valdes and Chelsea went on to lose the first leg of the last-16 tie 2-1.
The decision infuriated then Chelsea boss Jose Mourinho, who claimed Frisk favoured Barcelona. As a result, Frisk and his family received death threats.
Drogba was also dismissed in last year's Champions League Final with Manchester United for slapping Nemanja Vidic.
