Slaven Bilic insists West Ham have solved their crowd trouble issues ahead of Monday's rematch with Chelsea.
The EFL Cup clash between the London rivals in October was marred by coin throwing and fighting between rival fans.
But moves to improve the segregation, policing and stewarding have meant that since that night, such ugly scenes have all but disappeared.
Vice-chairman Karren Brady has worked tirelessly to put an end to disorder in the stands, and Bilic is confident she has succeeded.
"It is not that I think it - it is definitely the truth," the Hammers manager said.
"I have monthly meetings with Baroness Brady. We have talked a lot about that and I know how much effort, through her of course, has been put into solving those problems.
"She, or we, have done it so I am not expecting (a repeat).
"Of course there could be individual things that may happen, but the club has done a really great job regarding that. They have approached it since that game really seriously. We have done it, yes."
Bilic will come up against a familiar face when the Premier League-leading Blues arrive at the London Stadium.
Winger Victor Moses, who was on loan with the Hammers last season but struggled to hold down a first-team place, has just been rewarded for his fine Chelsea form with a new contract.
Yet Bilic says Moses' performances this term come as no surprise, and revealed that even former West Ham star Dimitri Payet marked him out for big things.
"I am glad for him," the Croatian added. "He was our player and we enjoyed that year.
"His potential, his characteristics, his strength, were always like amazing. His pace, quality on the ball and stamina is basically top, top class.
"Sometimes you have to push him to do it day in, day out, and now he is doing it. His place was anything but guaranteed at the beginning of the season. but he proved himself.
"I remember once I spoke to Payet during last season. Payet said that, even including himself, Victor is the best player that we have at West Ham."
