Leinster went top of the Pro12 last week with an impressive away win over the Newport Gwent Dragons and they'll be able to solidify that position with another victory. Between injuries and international call-ups they're missing a large number of players, but have massive depth to call upon. Having signed senior contracts during the week, Joey Carbey and Ross Byrne both start - at 15 and 10 respectively. It's a sign of Leinster's strength in backrow that they are still able to field an all international line-up of Ruddock, Leavy and Conan.
Scarlets struggled against Munster last week, earning victory thanks to the southern province's second half slip. Leinster are not likely to make the same mistakes, and will aim to put on a show in front of the home crowd.
