Hugh Farrelly gets down to the bare bones of Leinster's defensive problems in The Irish Independent.
"Former Leinster and Ireland prop Emmet Byrne has proven his forensic qualities as an analyst.
"When it comes to rugby, Byrne is a self-acknowledged anorak and not just about his primary area of expertise at scrum-time, but in every facet of the modern game. It's a microscopic attention to detail that is in keeping with a man who is four years into a degree which will end up with qualification as a surgeon.
"Leinster name their team to face Munster today and Byrne highlights the availability of Jonathan Sexton as a major issue. There is a long way to go in the Magners League and, if Sexton's quad muscle injury is still niggling him, there is a chance the out-half will be allowed another week to get ready for the immediate imperatives of the Heineken Cup."
