Bolasie moves to Villa Park on a straight loan arrangement.
He said: "My main aim here is to get this club promoted. A club of this stature has to be in the Premier League.
"I looked around both Villa Park and the training ground, and me and my family just said, 'wow'. It's Premier League everywhere you look.
"I'm here to make myself smile again and use all my ability to try and help the team. It's great to be here."
