Leinster coach Stuart Lancaster has told Joey Carbery he'd be better off staying at Leinster than heading north to Ulster.
Ireland's primary back-up to first-choice out-half Johnny Sexton, Carbery has been starved of minutes in the No.10 jersey at the RDS Arena with the World Cup now less than 18 months away.
The IRFU are believed to be keen for Carbery to make the switch rather than face another season spent at full-back.
"I've been involved in situations in England (with the national team) when a player has a decision to make, and my belief has always been that you put the player at the centre and you do what's right for the player," said Lancaster, who is helping prepare his side for Saturday's Champions Cup final with Racing 92.
"How it fares out, I don't know if I'm being honest.
"It's difficult, these things inevitably come up towards the end of the season.
"I come back to the point that I made, whenever I was in this position or involved with a player who had a decision to make I always tried to say, 'Right, what's the best thing for the player? Not what's right for this party or that party, what's right for the player'.
"As a consequence, I think Joey has developed brilliantly at Leinster and I think this is where he should stay.
"He's such a good player, a talented player. It's through no fault of anyone's that he hasn't played as much this year, he's been injured.
"But now is not the time for those conversations, not in a week as big as this."
