Gavin Henson is aiming to return to the Wales squad in time for next year's World Cup in New Zealand.
The 28-year-old centre last played at any level in March of last year and is currently on unpaid league from Magners League outfit the Ospreys.
But Henson, who has been linked with a move to the Aviva Premiership recently, believes he has time to force his way back into the national set-up before the tournament.
"I've never been to a Rugby World Cup which is coming up in 2011 and I'm thinking about training for that," he said.
"Hopefully I can get back into rugby, do well and get into the World Cup squad. It's the one thing that is not on my CV."
Wales coach Warren Gatland welcomes Henson's attempts to return to the game but stressed that he needed to get back in action as soon as possible.
Gatland said: "If he's going to put himself in the frame it's got to be sooner rather than later.
"If it's not until the New Year it's potentially going to be too late - he's been out of the game for a while.
"I haven't spoken to Gavin but it would be great to see him back on the rugby field. I had a quick conversation with him last year and we were going to meet up but we didn't.
"I have spoken to his agent and I just think it's a loss for the game. He's a talented player."
Henson has won 31 caps for Wales during the course of his international career, with his last appearance coming in their 2009 Six Nations defeat to Ireland.
