Toulon were the big winners in the Top 14 on Saturday, beating Racing Métro on the outskirts of Paris.
Castres racked up their seventh consecutive victory by winning in Montpellier while Stade Français were thumped in Agen.
Toulouse ran seven unanswered tries past Bordeaux to finish the weekend in third behind Castres and Clermont, who hammered Perpignan on Friday.
Elsewhere, Biarritz remain rooted to the bottom of the standings after being held to draw by newcomers Lyon.
Brive continued their revival with a bonus-point win over Bayonne.
Several of the clubs paid homage to their national squad ahead of Sunday's World Cup Final, with Agen - the home club of the late Albert Ferrasse, a former French federation chief and prime mover in establishing the World Cup - unveiling a massive flag and getting the fans to shout their support for Les Bleus.

Stade Toulousain 56-6 Bordeaux-Bègles
Stade Ernest Wallon, Toulouse
Toulouse started off slowly but stepped in up a gear in the second half, as Fijian wing Timoci Matanavu claimed a hat-trick in a convincing bonus-point win.
The visitors enjoyed the better of the first half and full-back Bruce Reihana's drop left the sides level early on. But Toulouse held a 11-6 lead at half time thanks to a try just before the break from scrum-half Nicolas Bézy.
Bézy extended the lead with his third penalty in the second half before Reihana saw yellow for a professional foul. Toulouse soon scored as the home pack rumbled over with Yannick Nyanga the ball carrier.
In was one-way traffic in the last quarter as Matanavu added a third try with Lionel Beauxis, starting his first game for Toulouse ahead of Luke McAlister, adding the extras with the first of his six conversions.
Matanavu bagged his second soon afterwards before Clement Poitrenaud added his name to the scoresheet with try number five after being put clear by Yannick Jauzion.
Matanavou has handed his third in the dying minutes when Yann David intercepted inside his own 22 and set the flying Fijian free. Wing Yannick Donguy added a seventh with two minutes left on the clock.

SU Agen 37-13 Stade Français Paris
Stade Armandie, Agen
A fantastic result for Agen - who flirted with relegation last season before assuring their place in the elite in the penultimate match - as they climb to fifth in the standings.
The hosts got off to a storming start, touching down for the first of their two tries in the first-half with just three minutes played through their captain, South African flanker Adri Badenhorst.
His compatriot Conrad Barnard converted to give them the ideal start in agme that would feature no less than five yellow cards.
Fijian wing Saimoni Vaka added a second in the 26th minute, a flowing backs move ending up with the 24-year-old flier coming in off his wing and cutting a swathe through the visiting defence to touch down.
Agen were sitting pretty at 23-6 at half-time but then saw two of their key players yellow-carded in the opening 10 minutes of the second half.
Hooker Jalil Narjissi was sin-binned along with Stade's prop Stanley Wright for a punch-up.
However, it was the sin-binning of skipper Badenhorst a few minutes later that really hit the hosts hard as soon afterwards Stade scored their first try, their Australian former Munster back Paul Warwick touching down under the posts before Julien Dupuy converted to make it 23-13.
However, Agen reacted brilliantly to these setbacks and halted the Parisian charge in its tracks with a third try, as they won the ball back from Warwick inside their own 22.
Ivory Coast full-back Silvere Tian cleared with a kick out to the wing where Vaka picked it up and ran 60 metres before offloading to scrum-half Maxime Machenaud who touched down - Barnard converted for 30-13.
Victory was completed with a penalty try and another conversion by Barnard to give Agen a memorable win.

Biarritz Olympique 15-15 Lyon Olympique
Parc des Sports d'Aguilera, Biarritz
Ailing giants Biarritz failed to get off the bottom of the standings as they were held to their second draw of the season.
Second-from-bottom Lyon led for a large part of the clash before a try by Biarritz's Argentinean World Cup returnee Manuel Carizza in the 61st minute brought them level.
It leaves the two-time European Cup finalists and five time French champions with just one win and two draws from their eight matches ahead of the return of their French internationals.
It was all square at 10-10 at the break after an evenly-contested first half.
Fijian wing Mosere Ratuvou opened the scoring with an early try for Lyon but Aussie full-back Dane Haylett-Petty's score leveled maters on the 20-minute mark.
Régis Lespinas slotted a penalty just before half time for Lyon to cancel out Marcelo Bosch's earlier effort.
LOU loose forward Vincent Clement crashed over to round off an attack started 60m out to put the visitors back in front but BO replied almost immediately as Pumas lock Carizza crashed over under a pile of bodies.
With scores locked at 15-15 going in the final minutes, the crowd held their breath as Lespinas sent a 80th minute penalty wide.
Biarritz: Haylett-Petty - Ngwenya, Baby, Burotu, Bolakoro - Bosch, Peyrelongue - Guyot, Gray, Lauret - Carizza, Thion (cap) - Gomez Kodela, Heguy, Buckle.
Replacements: Terrain, Watremez, E. Lund, Molcard, Lesgourgues, Bidabé, Couet-Lannes, Marconnet.
CA Brive Corrèze 30-10 Aviron Bayonnais
Stade Amédée Domenech, Brive
A second consecutive bonus-point win sees Brive climb into the top half of the standings. By contrast, Bayonne join Basque neighbours Biarritz in the relegation zone!
Brive led 7-0 at half time after flank Arnaud Mela scored just before the break following a drive from a line-out.
The hosts dominated in the second half, outscoring Bayonne threes tries to one.
Hooker Virgile Lacombe crashed over to extend Brive's lead soon after the restart but Bayonne wing Marvin O'Connor scored against the run of play to keep the visitors in touch.
But two tries in the final ten minutes from South African lock Retief Uys and wing Jacques Boussugue secured a deserved victory for Brive.

Montpellier HR 16-21 Castres Olympique
Stade Yves Du Manoir, Montpellier
South African Rory Kockott kicked seven penalties to give Castres their seventh successive victory.
Castres - who have failed to score a try in their last four matches - rejoin Clermont atop the standings, although they lose the lead on points difference.
Kockott took full advantage of Montpellier's ill-discipline as the hosts let slip an early advantage when Georgian backrow forward Mamuka Gorogodze scored a try in the second minute to help Montpol to a 10-9 half-time lead.
However, error after error by the hosts allowed Kockott to keep the visitors points tally ticking over but Montpellier's more enterprising play at least saw them take a defensive bonus point.

Racing-Métro 9-16 RC Toulon
Stade Yves Du Manoir - Colombes (Paris)
A vital win for Toulon as they keep in touch with the leading trio while Racing slump to their second loss at home.
Toulon fly-half Jonny Wilkinson captained the side and kicked 11 points while Aussie full-back Like Rooney scored the only try of the game on the stroke of half-time to give the visitors a 13-6 lead.
Racing dominated the second half but were unable to unlock the Toulon defence. Les Franciliens had the lion's share of possession for most of the game but their inefficient attack could make little use of it.
The hosts will rue a handful of missed penalties from Jonathan Wisniewski and will have to settle for a losing bonus point that keeps them in seventh place in the standings.
