West Ham United are set to rope in former Upton Park stewards to ensure a trouble-free game against London rivals Chelsea in the fourth round of the EFL Cup at the London Stadium.

Troubles have already flared up in recent fixtures against AFC Bournemouth, Astra Giurgiu, Watford and Middlesbrough at the Stratford venue this season.

The game against the Blues is going to be the biggest challenge for the stadium's security agency 'London Stadium 185' as about 5,000 away fans are set to attend the game.

West Ham supporters have already complained about LS185's handling of the games, and the agency doesn't want to take any chance in the London derby.

The agency has decided to employ former Upton Park stewards in 'areas to reflect experience and expertise' to ensure a smooth experience for the fans on Wednesday night.
