Wales star Gavin Henson believes he is about to enter the "last-chance saloon" as he prepares for his return as a Test match player.
Henson will run out against the Barbarians in Cardiff on Saturday after a season when he ended his long self-imposed exile from rugby through brief stints with Saracens and Toulon.
"It's great to be back," Henson said. "I am over the moon to get this chance - I have really missed it. I feel mentally refreshed. Yes, I would love to come into this match on the back of 20 games under my belt or something, but that's not the case.
"But I have got a chance here, and I will do everything I can on Saturday to hopefully force my way into these August internationals (Wales play England twice and Argentina), and then looking forward to the World Cup.
"At this moment in time, Wales is the most important thing for me. I have never been to a World Cup, and this is my only chance to try to make it right. I want to do everything I can.
"The World Cup is the biggest stage, and it is something I have missed out on twice. It is a huge driving factor in me - I really want to be on that plane.
"But I have got a lot to do. I am down the pecking order at the moment, which is fair enough. For me, the World Cup is the biggest spectacle, the biggest thing in a rugby career. I've never been to one.
"I have watched football World Cups a lot, and they are always massive occasions. I don't want to watch this rugby World Cup on television again. I want to be there - I would like to have an influence on the next one."
Henson has not being offered a new contract by Toulon, who also suspended him following an altercation with a team-mate after he helped the wealthy French club beat Toulouse in April.
He has not represented Wales since the 2009 RBS 6 Nations campaign.
