I truly am speechless after a match like the one we saw against Ireland on Saturday.
I was very satisfied about the start of the match as we displayed a very committed attack and a strong defence - even if two of the tries we scored were on a counter-attack.
But then, how come could we experience such a lapse of physical form in the second half?
It is true that the French had a very intensive week in terms of training and the players paid for that during the match. The Irish also battled their way back in superb style, but still, the French were burnt out.
Those 30 minutes give me a lot of concerns and uncertainties. Now the French have two weeks to recover and correct their mistakes.
Physically the players are exhausted. Maybe the coaches' speech is not communicative enough any more and some positions don't work any more.
There may be some sort of psychological weariness. And this is worrying when the tournament has just started.
It's going to get worse for us if we don't change things.
Coach Bernard Laporte also appears to be very nervous, with regard to his comments on the Stade de France crowd. He should take a step back.
I am dreading the match against Italy who are performing well in the RBS 6 Nations, and I am not even talking about England who seem on their way to winning the Grand Slam.
Against Italy we will have to hold on physically, take on board the tactical plan, vary our game, put pressure on our rivals, keep the ball and most of all adapt to the difficulties we encounter.
On Saturday it seemed that any pressure from our rivals was causing us to panic.
As far as Frederic Michalak - who left the pitch to fans' jeers in the 67th minute - is concerned, I think the bad reaction was for the whole team.
The public have the right to do what they want. They pay for their ticket, and the sudden change of game from the French team on Saturday probably scared them.
The most important thing is that those jeers become positive ones for the team in the near future and help France respond.
England Under-20s head coach Martin Haag was full of praise for his World Rugby Under-20 Championship-winning side after Harry Mallinder inspired them to a 45-21 win over their Irish counterparts and a third title in four years.
