West Ham will have police inside London Stadium for the first time when Chelsea visit in their potentially explosive EFL Cup tie on Wednesday night.
Despite a failure to installed Airwave radio systems inside the ground, officers will be deployed for the London derby in something of a compromise from the Metropolitan Police.
Clashes between fans inside the ground have led to West Ham asking for a police presence when 5,182 supporters of their cross-city rivals visit in the former Olympic Stadium’s biggest test so far.
And extensive talks between the Hammers, stadium operators LS185, local authorities and the Football Association have now provided a breakthrough to boost the security on Wednesday night.
