"What happened in the Ryan McBride Brandywell Stadium was a disgrace. Solidarity to all the Derry City FC supporters who were forced to endure this dangerous and fearful situation.
"Well done to the stewards and Derry City supporters for showing so much restraint. The PSNI have questions to answer. It's well-established that a section of CSKA Sofia supporters are fascists.
"They are well-known for their Nazi chants and salutes, racism, violence and disruption of games.
"They are not football fans, they are thugs. Alan Pardew parted ways as manager because of the racism and violence.
"Unfortunately this is normalised and tolerated by their club hierarchy and by UEFA bosses. These thugs didn’t come to Derry for football. They came to provoke the outcome that unfolded. They intentionally ruined an amazing occasion.
"This can never be allowed to happen again. Fascism, racism and thug violence must be rooted out of the people's game."
