Former champions Leicester Tigers and Toulouse meet in a winner-takes-all Sunday showdown at Welford Road for a prestigious quarter-final place.
Both sides, who have won the tournament six times between them, know a victory will win the Pool and secure a place in the last eight of the competition.
Four-time champions Toulouse lead the Pool from the Tigers by two points after their 35-14 bonus point victory over Italian outfit Benetton Treviso at home in the last round.
Leicester, who won the Heineken Cup back in 2001 and 2002, scrapped a 15-15 draw with the Ospreys in the Liberty Stadium in Swansea to keep their hopes of a place in the knock-out stages alive.
Toulouse recorded a comfortable 23-9 victory over Richard Cockerill's side in the first game between the sides back in October but will be aware the Tigers will be a different proposition at home in front of a sell-out crowd of 24,000.
The French giants, who won this tournament in 1996, 2003, 2005, 2010, have an impressive pedigree in Europe and last failed to reach the knockout stages of the Heineken Cup back in 2007.
The Tigers will be desperate to secure a place in the last eight, having failed to make the quarter-finals of European rugby's premier tournament for two of the last three seasons.
