2016 Champions Cup winners Saracens and runners-up Racing 92 will clash again on Sunday in what looks to be the match of the weekend in Pool 4, widely acknowledged as the 'Pool of Death'. Saracens have since lifted the trophy a further two times, including last season in Newcastle, while Racing 92 were again denied in 2018 as they fell narrowly short against Leinster Rugby. You can watch this clash live on Sunday from 15:15 GMT with coverage on BT Sport, FR2 and beIN SPORTS. Key quotes Laurent Travers (Racing 92): “We’re going to keep our feet on the ground and remain realistic. It’s a really top pool, with the reigning champions, a team that almost always features in the final or semi-final in the shape of Munster, and the Ospreys, who are one of the major provinces in Wales.” Mark McCall (Saracens): "Well, it’s a different kind of ground to go to. It’s under a roof and [it’s] the plastic pitch, which we’re a bit more used to. They’ve got a phenomenal side; we saw their game against Stade Français - they had a great win against them. They’ve got some real danger in their backline. You’ve got [Maxime] Machenaud and Finn Russell, two outstanding half-backs, and they’ve got a three-quarter line who can cause you real problems." https://twitter.com/ChampionsCup/status/1194942574336847872 Key facts
