Five French stars who could leave Ireland's Six Nations title hopes in tatters
Ireland's RBS Six Nations defence faces a massive test against Les Bleus on Saturday but which players should Joe Schmidt and his backroom team be paying particular attention to?
1) Yoann Huget
Born: June 2,1987 (aged 27) Pamiers,France
Height: 190cm (6ft 3in)
Weight: 97kg (15st 4lb)
Club: Stade Toulosain (Toulouse)
French caps: 34
Showed glimpses of his blistering pace against the Scots and is a clinical finisher.
He hits another gear once he crosses into the opposition 22, has good positional sense in defence and is very good in the air. A real threat.
2) Uini Atonio
Born: 26 March 1990 (aged 24) Timaru, New Zealand
Height: 197cm (6ft 5.5 in)
Weight: 155kg (24st 6lb)
Club: La Rochelle
Position: Tighthead prop
French caps: 3
The French front row was creaking until Atonio's introduction against Italy.
Very few Irish fans will have seen the New Zealand-born prop in action but Mike Ross has already warned that he can be a potent weapon for the French at the Avvia.
Ross described him as an "absolute monster" following his performance at the Stade.
3) Teddy Thomas
Born: 18 Sep 1993 (age 21) Biarritz, France
Height: 185cm (6ft 1in)
Weight: 90kg (14st 2lb)
Club: Racing metro
French caps: 3
Johnny Sexton will be telling his Ireland team mates all about his club mate from Racing but will also be hoping to exploit his poor positioning when Ireland are in possession.
He's a strong runner and has added subtlety to the French back three with his brilliant off-load game.
4) Wesley Fofana
Born:20 January 1988 (age 27)
Height:182cm (5ft 11.5in)
Club: ASM Clermont Auvergne
Position: Centre wing
French caps: 31
His centre partnership with the human wreckingball Mathieu Bastaraeud may look fearsome on paper but has failed to cause the problems that it should for opposition.
Fofana can be devastating in open play and steps well off both feet.
The Clermont centre could pose huge problems for Robbie Henshaw on Saturday but will need quicker ball from Camille Lopez to do so.
5) Thierry Dusatoir
Born: 18 November 1981 (age 33)
Height: 188cm (6ft 2in)
Weight: 100kg (220lb, 15 st 10lb)
French caps: 70
The French captain is a leader of men. His tackle count is rarely surpassed among his French team mates.
This may be because he has to compensate for laboured runners in the French tight five.
Ireland will attack around the fringes quite a bit at the weekend and hopefully won't be stymied by Dusatoir.
