The Metropolitan Police Service says a "tactical solution" is now set for matches at West Ham's London Stadium, which would see officers deployed inside the ground if needed for the EFL Cup tie against Chelsea.
West Ham moved from Upton Park into the converted Olympic Stadium for the start of the new season.
The club and London Stadium owner E20, along with stadium operators LS185, had requested a police presence at future matches following crowd disturbances during some Premier League fixtures at their new home, including those against both Watford and Middlesbrough.
Recent matches have seen an increased line of segregation and also more stewards, as well as improved levels of training.
