Seven tries to one. A 27-point differential. This Pool 1 Heineken Champions Cup encounter turned into a rout but Leinster were just three points to the good when Jonathan Sexton went down in the tackle four minutes after half-time.

England’s World Cup bid was just minutes old when Billy Vunipola launched himself into contact off the back of a lineout and Tonga’s Zane Kapeli floored him with a tackle that landed the big No 8 flat on his arse.
