Toulon

Clermont trailed 16-3 after 25 minutes when Leigh Halfpenny followed up three early penalties by converting a Charles Ollivon try.

However, the visitors came roaring back and moved ahead in the second half as Patricio Fernandez crossed twice in the space of two minutes.

Toulon were ultimately grateful for a 73rd-minute try from Mamuka Gorgodze, with Pierre Bernard adding the extras to ensure the lead changed hands once again.

Even then the drama was not over, Camille Lopez missing the target with a late drop-goal attempt that would have earned Clermont victory.

Racing beat Toulon in a showdown in Barcelona back in June to be crowned champions of France despite having Maxime Machenaud sent off, having also ended their European Champions Cup reign at the quarter-final stage.

The Paris club outdid Toulon again, consigning them to a third defeat of the season thanks in no small part to Imhoff at the end of a week in which France scrum-half Machenaud signed a new contract to run until 2020.

In other matches former Wallaby George Smith's Wasps sealed their last eight place with the English club recording a crushing 51-10 home victory over Irish side Leinster.

English club Wasps looked like they had beaten the defending champions when Guy Thompson scored in the corner, but Toulon replied with an injury-time try to Wallabies wing Drew Mitchell for a vital 15-11 win.

Running off a perfectly timed pass from Nonu, Mitchell hit the gas and sped away for the crucial try, and the win that takes Toulon to the top of Pool 5.

Nonu will play his first game for Toulon against Agen in the Top 14 on December 5th.

The double World Cup winner was unveiled to the media by the club today and told them he had sought plenty of advice before moving to the south of France.
