The Irish Independent's Hugh Farrelly looks at the bad blood between Leinster and the IRFU following the introduction of the cap on foreign signings.

"Leinster's war of words with the IRFU over the new policy on player recruitment escalated yesterday, with the province questioning the practicality of the selection process. The initiative, announced last week and due to come in for the 2013/14 season, is based on the principle of having two quality Irish-qualified players in each position among Leinster, Munster and Ulster. This means no more than one Non-Irish Eligible (NIE) player in any position, and on position specific deals, with no contract extensions or short-term deals for NIE players. Leinster coach Joe Schmidt and his Ulster counterpart Brian McLaughlin raised strong overall objections after their Pro12 clash on Monday, and yesterday Leinster manager Guy Easterby zeroed in on the workability of the selection process to decide which province gets the first pick on position."
