He told Villa's website: "I've got a chance to impress now and I want to try and make the most of it. I'm very excited to be at the City Ground and looking forward to hopefully playing a few games.
"It feels like a long time since I started a game. We haven't even played many reserve matches at Villa because of the club's UEFA Cup commitments.
"I've left a club fourth from top in the Premiership for one fourth from bottom in the Championship but that doesn't bother me. I look upon it as a challenge, it's nothing to be worried about and I can't see Forest being relegated.
"The club is trying to go forward and I'm looking forward to being part of that, even if it's only in the short-term."
