The 27-year-old defender is hoping he can make the switch Villa this summer after talks with the club, although he would be sad to depart Feyenoord.
"I cannot say too much," Vlaar told De Telegraaf.
"I have talked to our technical director Martin van Geel and I told him I liked the idea of moving to them.
"I feel at home in De Kuip, the club has had a lot of ups and downs, but there is still a warm feeling here.
"The stadium, the fans, my team-mates and staff. If the deal goes through, I miss them."
