Toulon head coach Bernard Laporte believes it is worrying for French rugby that despite his side's poor form, they sit top of the standings.
Laporte's men went to the Top 14 summit after an 18-12 win over Bayonne which saw All Blacks lock Ali Williams mark his debut with a yellow card.
The European champions were behind three times to a team they had crushed 50-10 and 59-0 on their last two visits. But they were saved by tries from wings Josua Tuisova and David Smith.
Jonny Wilkinson added eight points with the boot while former Crusaders fly-half Stephen Brett slotted over four penalties for Bayonne.
Toulon, beaten 22-15 by Castres last week, were plagued by indiscipline with lock Williams and South African scrum-half Michael Claassens both handed second-half yellow cards.
The 32-year-old, 77-capped Williams, who only arrived in France three days ago, was sin-binned for stamping in the 61st minute.
"What worries me is that we are first, it's worrying for French rugby!" said coach Laporte.
"We did everything we should not have done in a rugby match in 80 minutes."
