Victory by more than 14 points would mean that if Glasgow and Bourgoin are tied at the end of the group section the head to head scores would give the advantage to the Hughenden men.
Although beaten on Sunday there were enough signs in the Glasgow performance to suggest that victory this Friday is a definite possibilty although the leaking of soft tries will have to end.
Sale continue to have a miserable time in European competition being unable to reproduce their Zurich Premeirship form while Llanelli looked impressive in their win at Sale last Friday and will prove tough opposition in the Hughenden clash in the new year.
Glasgow will have to overcome both teams to keep their hopes alive but it all starts on Friday when defeat is not an option.
