Jamie Roberts' touted move to Harlequins will not affect his international career, says Wales coach Warren Gatland.
Roberts is expected to move from Racing Metro to the Aviva Premiership after the 2015 Rugby World Cup, having reportedly rejected a return to his former club Cardiff Blues.
If true, that would see Roberts breach the so-called "Gatland's Law", which favours Wales-based players for Test selection over those who choose to play elsewhere.
But Gatland told the BBC: "There's not a hard and fast rule as there is with England.
"There are exceptions where players who have been playing outside of Wales and there are one or two wildcards we could pick.
"They do play outside of Wales but they could be selected, but I think the long-term goal is to have a policy where, ideally, we pick players who are playing in Wales."
Roberts, 28, left Cardiff Blues in 2013 to sign a three-year contract, so must first secure a release from Racing before he can complete a move to England.
Gatland also confirmed the WRU has withdrawn its offer of a national dual contract to Taulupe Faletau after he missed a deadline.
Number eight Faletau has a year left on his current Newport Gwent Dragons deal and has been linked with a move to Aviva Premiership club Bath.
The 24-year-old British & Irish Lion said changing his agent had "delayed" signing a dual contract, which would be co-funded by the WRU and the region.
"It was disappointing he didn't sign a national dual contract," Gatland told WalesOnline. "It put me in a bit of a difficult situation when players and agents have been told a deadline.
"To go back on that when others have signed would not have been fair, we couldn't make an exception."
