Neither team could qualify from Pool 2 and reach the quarter-finals, but that failed to stop both sides from serving up an entertaining 10-try encounter.

Lyon scored nine of those themselves in what was eventually a one-sided score leaving them to return to Top14 action on a high.

Remarkably, the home side were two tries up inside five minutes with Hemani Paea and Albertus Buckle crossing the whitewash to give them an early advantage.

Romain Loursac converted both of those scores and from then on, it was one-way traffic.

Thibault Regard and Napolioni Nalaga both added further first-half scores, with Loursac adding another conversion for a comfortable half-time advantage.

That lead was one they never looked like relinquishing.

Replacement back Jerome Porical scored in both the 45th and 56th minutes and Paul Bonnefond, Curtis Browning and a penalty try completed the scoring.

Loursac ended up with three conversions, as too did Porical, as Lyon ended their pool stage adventure with a bonus-point success.

Peter Kimlin grabbed Grenoble’s only try just after the half hour mark, with Clement Gelin converting and booting two penalties but it wasn’t enough to get them anywhere near a victory.
