Holders Saracens will play Munster, Racing 92, and the Ospreys in the 2019-20 Champions Cup after the pool stage draw was made on Wednesday.
The Premiership champions are looking to defend the title that they have won in three of the previous four years, but face a tough group alongside Irish club Munster, French side Racing 92, and Wales’ Ospreys.
Last season’s runner’s up Leinster will face Lyon, Northampton Saints, and Benetton in Pool 1.
This season’s final will be held on May 23 2020 at the Stade Vélodrome in Marseille, France. Saracens won last season’s Champions Cup final at St.James’ Park, Newcastle — where they beat Leinster 20-10 for their third Champions Cup trophy.
This season marks the 25th year of the pan-European competition, and the sixth as its current Champions Cup format.
In the Challenge Cup, Cardiff Blues and Leicester Tigers will face each other in Pool 5– a repeat of the 2009 European Cup semi-final — with the draw also being held on Wednesday.
