Toulouse gained revenge over Leicester Tigers with a comfortable Heineken Cup win at Le Stadium.
Leinster's shock loss to Edinburgh at Murrayfield on Saturday had turned Pool Six into a two-horse race and the home side were looking to bounce back after their 14-9 defeat in the reverse fixture last week.
They managed to do so thanks to Clement Poitrenaud and Vincent Clerc's tries in either half.
In addition, Toulouse went five points clear in the group and denied the Tigers a losing bonus point which leaves them on the brink of exiting the competition.
This was Leicester's second away loss in the tournament after defeat in Dublin and Marcelo Loffreda's men will need a minor miracle to reach the quarter-finals.
Toulouse fly-half Valentin Courrent opened the scoring with a beautifully struck dropped goal, but was wide with a second attempt as the home side dominated the early exchanges.
As they did at Welford Road a week ago, the Tigers soaked up the early pressure and scored against the run of play as winger Tom Varndell took advantage of some poor defence to score in the corner.
The French heavyweights hit straight back, their star-studded backline producing a series of passes that only Toulouse can pull off.
Winger Cedric Heymans joined the line as the extra man and full-back Poitrenaud ghosted in out wide to get the crowd back on side.
Jean-Baptiste Elissalde matched his half-back partner with a dropped goal after a desperate Lewis Moody tackle denied Yannick Jauzion, but the three points were immediately cancelled out by Andy Goode as the French side infringed in front of their posts.
Elissalde banged over a late penalty goal to give the home side a 14-8 lead at the break.
But Leicester started the second half with real relish and after 43 minutes Goode reduced the deficit to just three by kicking his second penalty after Floran Fritz's dangerous bodycheck was spotted by Irish official Alan Lewis.
The three-time champions were instantly back on the attack and were only denied their second try by television match official John Sheehan who deemed Seru Rabeni's last-ditch defence had beaten the dive of Toulouse wing Clerc.
Leicester soaked up the pressure and as the match hit the hour mark, the Guinness Premiership outfit began to take a grip on the contest as the French crowd became restless.
But in typical fashion, Toulouse bounced back and Clerc equalled Michel Marfaing's club record of 24 tries in the Heineken Cup in the right corner.
After an initial burst by Jauzion on the left flank, Toulouse spread the ball wide to Poitrenaud and he supplied Clerc who fended off the Tigers triple tackle of Rabeni, Geordan Murphy and Martin Corry to expertly score.
And the French giants put the game out of Leicester's reach with Elissalde's penalty with 10 minutes remaining as Leicester prop Marcos Ayerza collapsed a scrum to hand Toulouse an 11-point lead and secure the win.
