Cardiff Blues fear Wales' find of the season Alex Cuthbert will turn down a six-figure offer to leave, possibly for France, at the end of the season.
Cuthbert capped a rise from the Blues development squad to play a scoring role in Wales' Grand Slam.
Reports have linked him with French Top 14 teams Toulon and Racing Metro.
A spokesman said: "The Blues have made Alex an attractive six-figure offer and we are aware that there are offers from other clubs on the table."
If he leaves, Cuthbert would join fellow Welsh internationals Gethin Jenkins, John Yapp, Richie Rees and Rhys Thomas in leaving the Blues.
Wales' four regions - the Ospreys, Newport Gwent Dragons, Scarlets and the Blues - are operating a
£3.5m salary cap
from next season.
Former Wales hooker
are to follow scrum-half
, British and Irish Lions prop
, ex-Scotland international
and ex-New Zealand centre
out of the Blues at the end of the season.
Jenkins will join Toulon, hooker Thomas is going to London Wasps while Yapp and Rees will play for Edinburgh next season.
Laulala is heading for Munster and Parks to Connacht.
During the season the Blues have also lost hooker Gareth Williams to enforced retirement and Gavin Henson to dismissal.
Veteran flanker Martyn Williams is also expected to confirm his retirement at the end of the season.
The Blues have announced centre
is to stay and recruited Fijiian prop
Campese Ma'afu and blindside flanker Robin Copeland
on two year contracts.
However, they also fear losing full-back
to a French club.
