Grenoble push Paris all the way.
Grenoble completed the group stages of their campaign with a comfortable 47-0 victory over I Cavalieri Prato at Stadio Enrico Chersoni.
That took them to 20 points and level with Stade Francais Paris but with the latter still to play London Welsh in the Pool 5 evening match to settle the battle for honours and quarter-final qualification.
Grenoble went top courtesy of their superior points difference in the head-to-head matches between the Top 14 rivals but Paris need just a point to qualify and deny Grenoble.
Howver, Grenoble, 59-3 winners in their Round 1 contest, made sure they did what they needed to do and made a fantastic start with lock Florian Faure, full back Joaquim Tucalet and centre Aloisio Butonidualevu crossing for tries in the first quarter to leave Prato struggling from the off.
And there was no let up from the Top 14 team in general and all-action hooker Larent Bouchet in particular as the front row forward went over for a quick-fire brace in the space of just three minutes.
Not to be totally overshadowed by a forward, Tucalet got his second and Grenoble's sixth for a clear 40-point lead at the break, with the bonus safely under lock and key.
The only real action for the first 25 minutes of the second period was the flood of activity from both replacement benches as the scoring came to a halt before substitute centre Rida Jaouho got Grenoble's seventh, Nicolas Laharrague adding his sixth conversion, to remind Stade they still have some work to do.
