**It’s undefeated Leinster who boast a formidable lead at the top of Conference A but the Conference B standings remain a far more tightly-contested affair.** Leo Cullen’s men have surged to a brilliant 13 wins from 13 matches to sit an almighty 20 points clear at the summit, but the opposite conference could hardly be tighter with just 18 points separating table-toppers Edinburgh Rugby and sixth-placed Benetton Rugby. Richard Cockerill’s side currently lead the way but their advantage is a slender one, just two points ahead of Munster while Scarlets sit third - ten points behind the Scottish outfit. And the joust behind Brad Mooar’s side is a fierce one, as the triumvirate of Connacht, Cardiff Blues and Benetton all sit within touching distance of the top three places.
