**The Guinness PRO14 season may be over, but the return of European action promises another feast of thrills and spills, with a repeat of last season’s showpiece finale arguably the pick of the Champions Cup quarter-finals.** \n\nFreshly crowned Championship winners Leinster lifted their third successive domestic trophy last time out, and Leo Cullen’s men will be itching to avenge their 20-10 defeat to the defending English champions in Newcastle last May. \n\nA lot has changed for the Londoners in the 16 months since, with a breach of the salary cap consigning Sarries to the second tier of English rugby from next season, adding more fuel to the fire ahead of this contest at the Aviva Stadium. \n\nWith a 100 per cent record in all competitions so far in 2019/20, Leinster will be confident they are well-equipped to progress to the last four of Europe’s premier competition for the fourth year running, having claimed the most recent of their four titles two years ago. \n\nWith Saracens’ season riding on this fixture however, the Irishmen won’t underestimate a side who have won the competition in three of the last four years, and will know victory will see them ranked favourites to go on and add European glory to their Guinness PRO14 success. \n\n# The Story So Far \n\nLeinster steamrollered their way through Pool 1, with victories both home and away against Northampton Saints, Lyon and fellow Guinness PRO14 side Benetton yielding 28 points - the most of any team in this year’s competition. \n\nA 33-19 bonus-point win over the Italians got things off to a perfect start, before Max Deegan scored the only try of a hard-fought clash with Lyon at the end of November, contributing to a valuable 13-6 victory. \n\nComprehensive wins over English giants Northampton Saints (43-16 and 50-21) generated plenty of festive joy shortly before Christmas, before the Dubliners rounded things off with a 42-14 win at home to Lyon, and an 18-0 victory away in Treviso.
