Leinster scrum-half Eoin Reddan has insisted that the RaboDirect PRO12 competition is not underestimated by Irish clubs.
Leinster have won three of the last four Heineken Cup titles, with Ulster also reaching the final of last year's tournament. However, Reddan has claimed that "RadoDirect games are massive".
"RaboDirect games are massive for individuals in terms of getting selected for those bigger games," he told Sky Sports News.
"We have a job to do this week. That job isn't to win, really, it is to do certain things that are asked of us, and those standards usually lead to victory.
"We have a massive responsibility, the guys who take to the pitch this week, to be very accurate in everything we do and if the result comes with that then great. But it's about getting the performance right and working on the specific things that we need to improve on."
Reddan has made 47 appearances for Ireland.
