Arrests and reported incidents of disorder at football matches in England and Wales last season were at their highest level for eight years.
There were almost 2,000 football-related arrests, the highest number since the 2013-14 season, according to Home Office figures.
Last season's disorder included players being approached after pitch invasions. A fan was jailed after running on to a pitch and headbutting Sheffield United captain Billy Sharp at the end of Nottingham Forest's play-off match against the Blades.
A Manchester City fan who ran onto the pitch and taunted Aston Villa keeper Robin Olsen on the final day of the season at Etihad Stadium received a four-year football banning order.
