Payet will once again be a key man against Chelsea with West Ham knowing a win will see them jump into the top four.
West Ham are set to finish above their London rivals for the first since 1996, and Bilic says this season’s exploits are no fluke.
“I don’t think it is a one-off,” he said.
“You always have one or two smaller clubs being there for a good part of the season or until the end of the season.
“And with the money involved and the scouting system and the training and planning, it doesn’t have to be a one-off.”
