Chelsea will learn the extent of the disciplinary charges they will face on Friday as a result of the fall-out of their Champions League clash with Barcelona.
UEFA disciplinary chiefs have been studying the reports from match referee Tom Henning Ovrebo and their match delegate and will decide on action later.
Didier Drogba and Michael Ballack are expected to face charges following their actions towards Ovrebo, and Chelsea could also be charged with failing to control their players after the match official was surrounded at the final whistle.
There were angry scenes with Chelsea furious at having four penalty claims turned down during Wednesday's 1-1 draw which saw Barcelona through to the final.
A UEFA spokesman said: "We will see the report from the referee and match delegate before deciding whether to take any action or not."
Chelsea manager Guus Hiddink and skipper John Terry were both scathing about the referee but UEFA will not be drawn into any discussion about his performance or suggestions that they did not want another all-English final.
The UEFA spokesman added: "We never comment on the performance of the referee."
Ballack was so incensed by one decision that he ran fully 40 yards protesting alongside the referee and was eventually yellow-carded.
Worse was to come on the final whistle when Drogba, who had been substituted in the second half, appeared from the tunnel to confront the Norwegian.
UEFA's general secretary David Taylor dismissed any suggestion of a conspiracy to avoid a repeat of last year's all-Premier League final.
