A very different set of boys in blue are in action this evening at the RDS as Leinster take on Opsreys in the latest fixture of their PRO12 campaign. The reiging champions are in for some match at the Royal Dublin Society this evening because this Welsh side only narrowly missed out on a spot in the play-offs last season, so we imagine they'll be determined to fight this one out to the bitter end. Leinster had the advantage last time, winning by 37 points to 19, but will they be able to do it all over again?
