West Ham boss Manuel Pellegrini is full confidence facing Manchester United at London stadium.
West Ham beat United 3-1 in the same fixture last season.
Asked if the current Hammers team is even better, Pellegrini said: "Maybe, but that doesn't mean we are going to beat Manchester United. We beat them 3-1 here and I hope we can get a win again.
"Man Utd played last night but they changed nine players so it will be a different team.
"We are in a good moment so, if we are playing against the big teams, we must show we can play in the same way."
