Liverpool's mayor has said some French police officers were seeking confrontation at last month's Champions League final in Paris.
Steve Rotheram said police were quick to threaten fans with their batons.
The head of policing at the final earlier apologised for using tear gas on Liverpool fans travelling to the Stade de France but said he had no alternative.
The fiasco has prompted uproar in France as well as the UK and Spain.
Liverpool fans, including families with children, were tear-gassed and pepper-sprayed outside the stadium by police ahead of the final between Liverpool and Real Madrid on 28 May.
