West Ham should play behind closed doors at the former Olympic Stadium if the violent scenes of Wednesday night's derby with Chelsea are repeated, an MP has said.
The Football Association has launched an investigation into the violence which marred West Ham's impressive 2-1 win over Chelsea in the EFL Cup fourth round.
Mark Field, vice-chairman of the all-party parliamentary football group and Cities of London and Westminster Conservative MP, says preventing future disorder must be addressed as a matter of urgency.
Field said in the London Evening Standard: "Within the next 14 days, the board of West Ham United FC should present a detailed plan to the FA and Premier League outlining what they are going to do about security.
"None of these problems were unforeseeable, given the nature of the stadium and difficulties with policing large footballing crowds.
"There have been some clear failings and they now need to move with urgency to deliver a plan about segregation and broader public order issues.
"If there is a repeat of the violence, the next two or three home games for West Ham should be played behind closed doors."
Sports Minister Tracey Crouch added: "No-one wants to see a return to the dark days of the late '70s and '80s.
"It is completely right that strong action is taken and that anyone involved in last night's trouble is banned for life."
