Cardiff Blues and Wales flyhalf Gareth Anscombe's national dual contract comes to an end after the World Cup in Japan and the Blues are keen he signs a new deal.
However, Anscombe's form will attract interest from other clubs with Ospreys already being tipped as potential destination.
Cardiff Blues have since commented on rumours and are confident they can persuade the Wales fly-half to stay at the region next season.
"We have been talking with Gareth and his agent for quite a while and he understands we are very keen to keep him," said head coach John Mulvihill.
"It needs something quite special for him to move."
"We just work on making sure, when we give our offer, it's the best we can give. I'm sure him and his agent will be happy with that.
"He's an integral part of my group and our success going forward. He acknowledges that and all his mates play for the Blues, he lives in the area and his mum is from Cardiff."
Mulvihill believes staying in Wales to play for the national side will be a key factor in Anscombe's decision.
"He doesn't want to go and play in the English Premiership because he wants to play Test rugby here for Wales, not just for this World Cup, he wants to go on," said Mulvihill.
"He believes he could play again in four years so we just need to sit down and iron out the final detail. Hopefully, we will have a decision sooner than later."
