Vlaar thrilled by Villa talks
He told De Telegraaf: "I was on Sunday in Birmingham to have talks with Paul Lambert and left with a very positive impression.
"I feel at home at De Kuip and although both me personally and the club have had a lot of ups and downs, we have maintained a good relationship. The stadium, the fans, my team-mates and staff... if the deal goes through I will miss them."
Vlaar has won nine caps for the Netherlands and, should he sign, will boost Villa's defensive ranks, which were weakened by Carlos Cuellar's move to Sunderland.
