Maxime Medard has urged caution against an in-form Wales side as France travel to Cardiff on Friday in their Six Nations clash.
France have won their opening two games of the Six Nations with slim victories over Italy and Ireland, prompting hopes of a first Championship and Grand Slam since 2010.
But France have not beaten Wales since the 2011 World Cup and have lost four successive Six Nations Tests and Medard knows how quick Wales can be.
"Wales are a very powerful team in both attack and defence, they come up very quickly, and we know this match will be completely different to the first two that we played," he said.
"The truth is, at the moment, we have got nothing, we won two matches while struggling.
"We have not won anything yet, and with a dangerous trip to Wales, we have
nothing to brag about at the moment."
