**There promises to be plenty of fireworks in Dublin on Monday night, as two of the Guinness PRO14's biggest hitters go head-to-head looking to extend their respective winning runs.** \n\nTriple defending champions Leinster - unbeaten in the Championship since April 2019 - have made the perfect start to their defence so far in 2020/21, with bonus-point wins over Dragons, Benetton, Zebre, Glasgow Warriors and Ospreys. \n\nLast year’s Semi-Finalists Edinburgh have won their last two matches against Scarlets and Cardiff Blues after three opening defeats, and could become only the second side to beat the Irishmen at the RDS Arena since April 2018 with a win. \n\n**What’s at stake?** \n\nLeinster were unstoppable as they completed the 2019/20 Guinness PRO14 season without defeat, and Leo Cullen’s men have hit the ground running as they attempt to follow up that feat in similar fashion this season. \n\nA perfect start has yielded 25 points to put them top of the Conference A rankings, but with last year’s runners-up Ulster breathing down their neck with an unbeaten start of their own, the Dubliners will be determined to maintain their authority.
