Not happy.

Leinster are understood to be furious that Leo Cullen was pressurised for a decision on the futures of Joey Carbery and Ross Byrne at the province during the week of their semi-final clash with Scarlets.

Peter O’Reilly of The Sunday Times is reporting that Ireland head coach Joe Schmidt and IRFU performance director David Nucifora visited Leinster’s training centre last Sunday morning to inform Cullen that he must release either Ross Byrne or Joey Carbery to Ulster as a replacement for Paddy Jackson.

A decision was put on hold, but following Leinster’s demolition of Scarlets, it appears they must now act fast and decide who they want to keep for next season.

Carbery is highly rated, and can operate in a number of positions. But Leinster could be left without a ten during international windows if they let Byrne go and keep Carbery.

Either way, it’s looking increasingly likely that one of the two will make the move up north. If either move, it will mean at least nine Leinster products will be at Ulster next season, either in the senior squad or the academy.
