Samir Carruthers has joined MK Dons on a three-year deal.
The 21-year-old midfielder spent most of last season on loan at the Stadium MK, making 28 appearances before his spell was cut short because of injury.
Carruthers came through the club's academy and skippered our U19 side to NextGen Series glory in 2012-13.
He made three appearances for Villa's first team, all of those coming in the 2011-12 season.
