Vlaar arrived at Villa Park yesterday following a £3m move from Feyenoord.
The 27-year-old said: “I talked to Robin during the European Championships, when we were together with the national side. He said that if I got the chance to play in England, I should get myself over here – and here I am!
“It’s a big loss if Robin leaves England because he is a great player. No, he didn’t tell me where he might be going.”
