Bundesliga club Cologne will attempt to identify and sanction fans responsible for flares and on-pitch clashes with police after Saturday's Rhine derby defeat at Borussia Moenchengladbach.

Masked Cologne supporters wearing white overalls stormed the pitch after Granit Xhaka's injury-time winner for `Gladbach, leading to violent scuffles that left several security staff and one police officer injured. Two arrests were made and some fans were identified.
