LONDON -- West Ham and Chelsea have both publicly condemned the crowd trouble that marred the closing stages of Wednesday's EFL Cup fifth round tie at the London Stadium and pledged to take action against any supporters found to have participated in the disturbances.
Slaven Bilic's men emerged 2-1 winners from the first London derby to take place at the former Olympic venue, but the match was overshadowed by clashes that flared in the wake of Edimilson Fernandes' 48th-minute goal that put West Ham 2-0 up against their rivals, and escalated in the final minutes.
A number of plastic bottles and at least two chairs were ripped from their holdings in the Sir Trevor Brooking Stand and thrown between both sets of supporters, who squared off behind a thin line of stewards.
