Leonid Slutsky refused to condemn the Russia fans who attacked England supporters at the end of the 1-1 Euro 2016 draw in Marseille on Saturday.
Hundreds of Russia fans burst through a flimsy security cordon to attack their English counterparts at one end of Stade Velodrome.
Helpless England supporters were forced to escape by leaping over high barriers with police absent from the ugly scenes.
But Slutsky insisted he had not seen the trouble at the final whistle shortly after Vasili Berezutski had cancelled out Eric Dier's opener.
He said: "I'm not really up to speed with what's going on so – we were preparing on the game – but in any case that's clearly not the best thing for football."
Pressed on the matter, he added: "I can't really comment."
Russia were handed a six-point penalty and suspended for the duration of their Euro 2016 qualifying campaign following incidents during the game against the Czech Republic at Euro 2012.
Omnisport understands UEFA will study reports of Saturday's violence before deciding on further action, but Slutsky refused to acknowledge the sanction ever existed.
Slutsky said: "What problem did we have in the qualifying campaign? What problems were there?
"I don't remember that situation, I think you're mistaken."
Slutsky was more forthcoming about his team's on-field efforts, although he admitted they were second best for long periods.
"I can thank my players because they were very much in the game right to the death and despite the pressure they were able to score even though it's always difficult at that stage of the game," he said.
"They kept on scrapping to the end and saved a result. I'd like to point out that England dominated but we were able to contain them and their dangerous forwards."
