... because of alleged racist chanting towards Yaya Toure.
The 30-year-old reported the incident to referee Ovidiu Hategan during the Champions League tie, and UEFA responded by charging the Russian club with "racist behaviour of their fans" the following day.
A seven-strong panel, headed by Austrian chair Dr Thomas Partl, will meet at UEFA's headquarters in Nyon, Switzerland, on Wednesday afternoon to decide whether Toure was abused.
The hearing, which is held in private, will look at documentary evidence submitted by both sides. Neither Toure nor any representatives from the two clubs involved will be present.
