Champions Cup: Holders Saracens in tough pool with Munster, Racing 92 & Ospreys
European and Premiership champions Saracens will meet two-time winners Munster, French giants Racing 92 and Welsh side Ospreys in the pool stages of next season's Champions Cup.
They all meet in a tough Pool Four, while Pro14 winners Leinster face Lyon, Northampton and Benetton in Pool One.
Top 14 winners Toulouse face Connacht, Gloucester and Montpellier in Pool Five.
Bath and Harlequins contest Pool Three with Clermont Auvergne and Ulster.
Elsewhere, Premiership runners-up Exeter come up against Glasgow - the former club of Exeter's new signing Stuart Hogg - Sale Sharks and La Rochelle.
In the Challenge Cup, Leicester will face Cardiff Blues, Pau and Calvisano as their pool stage opponents, the Tigers having failed to qualify for the Champions Cup following a dismal Premiership season.
Wasps were grouped with Edinburgh, Bordeaux-Begles and Agen, while newly-promoted Premiership club London Irish will tackle a testing pool that also features Scarlets, Toulon and Bayonne.
The first round of European games take place on 15-17 November.
