Arsene Wenger believes disorder at West Ham has damaged the argument for safe-standing areas at English football.
Arsenal manager Arsene Wenger says there is nothing worse than playing behind closed doors amid the prospect of a stadium ban being imposed on West Ham.
The issue of hooliganism at English grounds has raised its head once more this week following the violence at London Stadium that marred West Ham's EFL Cup win over Chelsea on Wednesday.
Missiles were thrown from both sets of fans before scuffles broke out on the concourse.
West Ham are studying CCTV footage of the incident while the Football Association have also launched an investigation.
