The former Manchester United and Republic of Ireland midfielder is believed to be in talks regarding an assistant manager role at Villa Park.
Paul Lambert is eager to bring fresh faces into his backroom staff, and Keane's vast experience at the highest level would make him a useful addition.
He would be looking to combine his duties at Villa with those under Martin O'Neill with the Irish national side, but any input at Premier League level would be most welcome.
Vlaar certainly sees it that way, with the Dutch defender - who is currently away on World Cup duty - hoping he will return to England to find Keane at Lambert's side and Villa ready to push on into an exciting new era.
The club captain said in the Birmingham Mail: "I don't know him as a person, I know him as a player.
"He has a lot of fighting spirit, and I think that would be really good for us.
"He's a very strong character. I think everybody has a lot of respect for him and I look forward to it."
