With Ulster eyeing up a play-off spot after tonight's victory over Connacht, a win for Leinster can close the gap on Pat Lam's side at the top of the Pro12.
Standing in their way is their old foe Munster and speaking on tonight's show, former Leinster fly-half Felipe Contepomi said that they were a side from which he learned a lot.
"For me, obviously Munster were our great rivals, more so for the style of rugby and so on. But I always said that Munster taught Leinster a lot of things.
"Munster players were a great example of passion and how you play for a jersey. I think that now Leinster have that and you can see in the last ten years how they have developed and grown into that sort of team.
"I see a lot of similarities between Irish and Argentinian people. A lot of those players play with a lot of passion and pride for the jersey.
"At that time I think Munster was the team, when they were the champions of Europe. How they played and won those type of games on the big occasions, that was all down to passion.
"Leinster had their style of playing, but when you add that passion into the booklet I think they were unstoppable."
