Today is just another game for Villa captain Vlaar.
He told The Sun: "There's no such thing as a 'big' game for me.
"I think it's bad if you only get motivated for 'big' games. So I'm as motivated in training as I will be playing on Saturday.
"How do I keep Van Persie quiet? Don't give him any chances!
"I join up with the Dutch national squad on Monday for our next match against Germany in Amsterdam.
"There's a good chance we will be on the same flight. But we won't make fun of each other. We'll talk about our game but always with respect."
