Jacques Brunel admitted France had been too inconsistent despite a final day victory over Italy to round out their 2019 Guinness Six Nations campaign.
Les Bleus were put under a lot of pressure in Rome but eventually emerged with a 25-14 success.
That win came thanks to a Damian Penaud try at the death, a couple of minutes after the winger had denied Marco Zanon as the centre looked set to score on debut.
As a result, France finish the campaign fourth, with wins over Italy and Scotland, but heavy losses in England and Ireland, as well as their dramatic opening-day defeat to Grand Slam champions Wales.
And while Brunel was relieved to come away with the win, he admitted France had committed too many errors at the Stadio Olimpico.
He said: “We were under pressure. It’s been there since the start of the Championship and we’ve had displays which have not reassured us. Some were disappointing, we know.
“We were not able to counter the Italian pressure because of our mistakes and errors at the start of the game. But we were able to resist and take the chances that came our way.
“We would have liked to have controlled the game more but we were not able to do so and suffered as a result.”
The win was enough to push France ahead of Scotland in the table but Brunel was aware that they have a lot of work still to do.
He added: “The Championship is a disappointment. We are disappointed with our campaign. We were too inconsistent, not playing well sometimes, and sometimes playing badly.
“Like today, we had moments where we lacked control and other sparks. We were too inconsistent to be satisfied.”
