Wasps fly-half Nicky Robinson believes Luke Charteris could be the next Wales star to play his club rugby abroad.
Lock Charteris has attracted interest from a number of French teams, according to his agent, and is considering a number of options.
"He's had a very successful World Cup and that has opened up a few other doors for him," said Robinson.
"You'd be surprised if someone like him didn't want to go and have a look at what there is to offer out there."
Charteris is out of contract at Newport Gwent Dragons at the end of the season and is expected to decide where his future lies over the next few weeks.
Perpignan, who signed James Hook from the Ospreys at the end of last season, have emerged as strong favourites to land the 28-year-old.
The four Welsh regions are unlikely to match any contract offer from lucrative French clubs, and Robinson believes Charteris could well decide to benefit from the exposure gained from his impressive World Cup performances.
"It's all about timing in sport - on the pitch and off it. He obviously played well at the right time," said Robinson, who has won 13 caps for Wales and who moved to Wasps via Gloucester after leaving Cardiff Blues.
"A lot of clubs obviously watch the World Cup and if you see players performing well at the highest level - and you don't get any higher than the World Cup - then you're going to look to strengthen your side.
"And especially with France, where the set piece is so important, someone like Luke who's so good in the line-out is going to be a wanted man."
If he opts to move to France, Charteris would become the fourth 2011 Welsh World Cup player to be plying his trade across the English Channel.
Hook, full-back Lee Byrne (Clermont Auvergne) and scrum-half Mike Phillips (Bayonne) joined the French Top 14 following the World Cup.
But their moves were followed by a warning from Wales coach Warren Gatland that Six Nations selection could prove difficult for some players based outside Wales.
Robinson believes his own hopes of being selected for Wales have been hampered by moving to England, and says that making the decision to play outside Wales is never taken lightly.
"It's amazing how quickly things change - a few injuries, you play well in a couple of games and all of a sudden you're first-choice.
"But because the international set-up is so fragile, if your form isn't there you could be out of it.
"It's hard to stay in Wales just to play for Wales if that's not a guarantee, which of course it isn't.
"If the sacrifice might be not playing for Wales - that's a tough decision and a tough call he [Charteris] might have to make."
