Westwood signed a four-year deal with Villa yesterday.
"I see myself as a Michael Carrick-type of player, someone who stays out of the limelight and keeps it simple, retaining the ball and laying it off to team-mates and from the conversations I've had with the new manager I think that will fit in perfectly here," Westwood said.
"He said to me that he's looking for younger lads to work with him, step up and lift this club to the next level and I'm really looking forward to the challenge.
"This is a fantastic football club, a massive club and I can't wait to get started really.
"It's a bit surreal right now but I'll get out training with the lads tomorrow morning and take it in my stride."
