Top seeding for the knockout stage will be the target for the two teams, with home advantage on offer to the highest ranked sides from the pool stage.

"To get through with a round to spare is excellent, especially when you consider we were in a group with two teams that were in the final of their domestic competitions last year. We are pleased we won [against Castres], but we want to stretch ourselves. We want to win at home." Saracens prop Marco Riccioni: “They were very physical last time. We have to bring that physicality back on. I think we’ve shown we can be more physical than anyone. We have to get into this mentality.” Edinburgh Rugby
