The former England international is set to play his final game for Villa at Norwich next Sunday as his three-and-a-half-year deal is completed.
He said: "I've enjoyed my spell at Villa. We got to the Carling Cup final, and an FA Cup semi-final. It gave me the chance at Wembley again so I can't complain.
"But there are no contract talks with Villa so I will be looking elsewhere.
"I haven't got a club (lined up) to be honest. Obviously my contract is up so I just take it day by day and see what crops up.
"But I want to carry on playing. I'm 34, I still feel I can play so I don't see why I need to retire just now.
"I still want to play at Premier League level. From when I started, I always said I wanted to play at the highest level wherever that might be. You always strive for that."
