The Dutchman is in Foster's fantasy football line-up.
But he has sidelined RVP this weekend in the hope the Manchester United hitman will not add to his 16 goals this term.
Former United keeper Foster, 29, said: "Van Persie is in everybody's team, isn't he? He's definitely in mine.
"When United really play well with their best attacking team, it's a frightening thing to come up against.
"But I'm going to put them all on the bench for this game and put all the West Brom defenders in for clean sheet points!
"I think Van Persie would have improved any team.
"He's right up there as one of the top strikers in the world.
"And with a team like United, who are a very attacking team anyway, it's a dream come true for the fans there to have him."
