And the Cardiff Blues are in the Pool 6 driving seat, four points clear of Gloucester Rugby with their Kingsholm Sunday showdown potentially the clash of round 5.

- No team has qualified as pool winners on less than four wins
- No team has qualified as one of the best runners-up on less than four wins
- Since bonus points were introduced no team has qualified as a Pool winner on less than 18 points (Stade Francais in 2003/04)
