CSKA was never able to win a single match in the group stage. This is an absolute anti-record for Russian clubs in the Europa League.
All teams that made it to the group won at least one meeting. Even the modest Krasnodar Kuban managed to win in 2013, beating St. Gallen.
In the current Europa League, CSKA is not alone without victories. Also, “Garabagh”, “Dundalk”, “Ludogorets” and “Gent” did not win a single match.
