Uefa has made the decision to open cases against both Slovakian outfit Zilina and Russian powerhouse Spartak Moscow following the events at their Champions League encounter last Wednesday.
The disciplinary case opened against Spartak is for the improper conduct of their supporters ahead of the match against Zilina. Aside from invading the pitch ahead of the game, fireworks were set off and thrown and stewards were attacked by supporters.
Meanwhile, a case was opened against Zilina because of improper conduct from the players. The Slovakians were handed five yellow cards against the Moscow side.
Additionally, they face charges of insufficient organisation, related to the pitch invasion by Spartak Moscow fans.
Uefa has announced that each club's case will be discussed and dealt with by the Uefa Control and Disciplinary Body at its meeting on Thursday, December 16.
