West Ham boss Slaven Bilic condemned supporters who clashed with Chelsea fans during the EFL Cup fourth-round match at the London Stadium on Wednesday.
Skirmishes broke out towards the end of the Hammers' 2-1 win as police and stewards battled to maintain segregation behind the goal being defended by West Ham.
Bilic, perhaps understandably, wished to focus on the fine performance of his team and was frustrated at facing questions about the "unacceptable" behaviour of a minority.
"I noticed it, of course," Bilic said. "The game was on. I was more concentrated [on the game]. I don't know what happened. But whatever happened, we are totally against it as a club as a team.
"For those kind of things to happen, especially in England, is unacceptable."
West Ham also released a statement, which read: "West Ham United and London Stadium partners unreservedly condemn the behaviour of individuals involved in incidents during this evening's fixture with Chelsea.
"Whilst quickly brought under control, the club, in line with its clear zero tolerance policy, will work closely with London Stadium, the Metropolitan Police Service and Chelsea to identify the individuals involved."
Cheikhou Kouyate and Edimilson Fernandes scored the goals for the Hammers as they set up a quarter-final trip to Manchester United.
Bilic told Sky Sports that he was pleased with his team's performance, even if it was against a Chelsea side missing several first-team regulars.
"The way they played against Leicester and Manchester United was unbelievable to watch but we matched them," he said. "They didn't have the same team, but they are all great players.
"Maybe that helped us because the team that went out hadn't played together and we used that opportunity. But they would have had trouble with us even with their strongest team because we played really well, especially in the first half."
