Gareth Thomas says his successful return from injury this season has rekindled his desire to captain Wales.
Thomas has proved to be an inspirational Wales captain
"If I am made captain, I will be thrilled," said Thomas, who had been out since February after mini-stroke.
"If there is to be a new captain, I will give him as much support as I can. My one goal right now is to get back into the Welsh jersey.
"After three big games for Toulouse in rapid succession, it's great to know there are no problems with my fitness."
Thomas returned to competitve rugby last month when he played 50 minutes for Toulouse's reserve side.
The 32-year-old felt no ill-effects and has since featured in all of Toulouse's matches in the French Championship, scoring his first try of the season in Sunday's 20-3 win over Biarritz.
Wales coach Gareth Jenkins will reveal his choice as captain next month, with Thomas a leading contender alongside fly-half Stephen Jones and prop Duncan Jones.
Thomas led Wales to the Grand Slam in 2005 and went on to captain the Lions in New Zealand after Brian O'Driscoll's first-Test injury.
Jenkins, who took over from Mike Ruddock in April, made Duncan Jones captain for this summer's two-Test tour to Argentina.
