Vlaar has urged Van Persie to snub a move to Juventus after admitting it was his fellow Dutchman who helped him decide to move to England.
"I really don't know where he is going. I haven't talked to him lately," said Vlaar. "I just hope he stays in England so I can face him. I've trained against him with the national team and he is a great player.
"It would be a big loss if he leaves England."
