Villa boss Lambert delighted with Vlaar capture
Lambert is convinced Vlaar's class and pedigree will ensure he is a success in the Premier League.
The Scot said: "Ron is a really good defender and he has a wealth of experience for both Holland and a big football club in Feyenoord, so I'm delighted we have got him here to Villa.
"I like the way the guy wants to do well. He's hungry and he wants to succeed. He's also a really good, strong defender and hopefully we will get the benefit of him in our team.
"He's been in the Dutch international set-up and was part of the Euros, so he's a proper player. He'll bring something to the club, no doubt about it."
