Toulouse head coach Guy Noves has admitted his side face a tricky final pool game against Gloucester next weekend with the four-times Heineken Cup Champions needing to get a result at Kingsholm.
A hard-fought bonus point victory over Connacht on Saturday put Toulouse in pole position in Pool 6, two points clear of Harlequins.
Whilst Toulouse travel to face the Cherry and Whites on Friday, Harlequins head to Galway and Noves knows his side still has work to do.
"We have to win in Gloucester and we knew that before today," he said.
"We know that it is not going to be easy but if we don't qualify we know it is because of the home defeat to Harlequins.
"But we still have matters in our own hands and the focus of the team is to win in Gloucester and that's a nice challenge for Toulouse and its going to be an interesting game."
