A week before they are expected to take the field in Bermuda Saracens emulated Leicester Tigers and Wasps becoming only the third English team to clinch a domestic and European double.
Saracens retained their Premiership title by beating Exeter 28-20 at Twickenham, adding the league crown to the European Champions Cup they won earlier this month.
Wasps were the last side to achieve that feat in 2004, while Saracens are also the first side to win back-to-back titles since Leicester in 2010.
