The battle between the Worcester Warriors and Perpignan will go right down to the wire in the final game of this Pool as both sides still have ambitions of a quarter-final place.
The Warriors returned home from Italy with a 80-17 victory over part-timers Rovigo at the Stadio Mario Battaglini, where they ran in 12 tries with wing Josh Drauniniu scoring a hat-trick.
Perpignan kept their own ambitions of place in the last eight alive with their own 50-15 bonus point victory over Spanish part-timers Bizkaia Gernika RT at the Urbieta Rugby Sport Centre.
The Catalans, who reached the 2003 Heineken Cup final, scored eight tries but their win means both sides will be keeping an eye on each other's final game with both side on 20 points.
The Worcester Warriors face Bizkaia Gernika RT at home at the Sixways Stadium and Perpignan host Rovigo at the Stade Aime Giral and both sides will be looking for wins to keep the pressure on each other.
If both teams cannot yet be separated on points after the final game of the Pool, the number of tries scored in their head-to-head games will then come into play and Perpignan have a 3-1 try advantage over the Warriors.
