Dimitri Yachvili insists France can recover from their shock defeat to England and retain their RBS 6 Nations crown.
Les Bleus remain in pole position - and are 2-5 favourites with the bookmakers - to bounce back against Scotland in Paris on Saturday and hold off the challenge of Ireland and a revitalised England.
It could all come down to points difference and Yachvili knows Scotland will be no pushovers after going so close to toppling Ireland in Edinburgh.
'There is no Grand Slam but we still can win the Six Nations tournament,' said the Biarritz scrum-half.
'It will not be easy because Scotland are getting better and better. They didn't win on Saturday but they played very well and will be very dangerous next week in France.'
Yachvili knows France will need to re-discover their attacking flair if they are both win and score the necessary points against the Scots.
They were strangely subdued against England and were forced to rely on the kicking of fly-half David Skrela and then Yachvili when his half-back partner succumbed to an ankle injury.
Yachvili's third penalty, which matched Skrela's earlier efforts, edged his side back in front at 18-16 after 58 minutes and took his points haul in four matches against England to 65 but the home side finished strongly to earn the spoils.
'We are disappointed because we knew we could win but we made too many mistakes and England deserved their win,' said Yachvili.
'They had to win and they played well. They put a lot of pressure on us and we didn't attack very well We could not go forward and that took the pressure off the English. Because we were always going backwards, it made it hard to win.'
France led 12-9 at half-time but fell off the tackles far too easily to allow young fly-half Toby Flood and centre Mike Tindall to score second-half tries.
'We are really disappointed,' added forward Sebastien Chabal. 'Before the game, we were quite confident about our rugby but we didn't play at all. We didn't get three phases in a row.
'We still can win the tournament but it will be difficult. We are four or six points in front of Ireland but the most important thing is to win next weekend.
'We must go back to our strengths and get our kicking strategy and set pieces right, which was not the case today.'
