The Australia international revealed the opportunity to work every day with players of the calibre of Bent made Villa such an attractive prospect.
"There are big names here. I was more than aware of the quality players at Villa, even though I've obviously come from the Eredivisie in Holland.
"Just look at Darren Bent, who's a top-quality goalscorer and a proven England international. It's certainly exciting times. I can't wait to get involved, meet the guys and get stuck into life at Villa."
