Gloucester kept up their unbeaten record in Pool 1 after they completed back-to-back victories in their double-header with Premiership rivals London Irish at Kingsholm.
The West Country giants came away with a one-sided 47-3 demolition in their home tie and are now seven points ahead of the Exiles with two games to play against French sides Mont de Marsan and Bordeaux-Begles.
Wing Shane Monahan enjoyed a rare old afternoon and crossed for four of Gloucester's six tries in their comfortable bonus point win in front of a home crowd of 10,535.
Gloucester will have one eye on making sure they earn themselves a vital home daw in the quarter-finals but will be aware they are not completely clear of London Irish and Mont de Marsan.
Mont de Marsan kept their own slim hopes of a place in the last eight alive with their 18-7 victory over Bordeaux-Begles in the French derby clash at the Stade Guy Boniface.
London Irish travel to face Mont de Marsan in France and the result of that fixture will see the end of one or their qualification ambitions in Europe over for another season.
