France Women play host to England Women in Grenoble on Saturday for a potentially decisive clash in the Women’s Six Nations.
Both sides have picked up 15 points from a possible 15 in the competition to date, leaving them in good shape for the overall title in case of victory in the east of France.
As it stands, it is England who lead the way, with a points difference of +122, while France are not far behind with a +104.
And with third-placed Ireland on nine points, the winner of this game will be within striking distance of the title and a possible Grand Slam in Round Five.
Les Bleues produced arguably their best performance of the Championship to date in Round Three when they beat Italy 57-0, while England impressed away to Scotland, running out 43-8 winners.
And the teams will now go head-to-head after a pair of thrilling meetings in 2017, knowing that the victors will be on the brink of Championship success.
Last year at Twickenham it was France who dominated early, only to let a 13-0 half-time lead slip as England roared back in the second half, running out 26-13 winners.
And it was the same outcome at the Rugby World Cup in the semi-finals, when the Red Roses claimed a 20-3 victory which was much closer than the final scoreline suggested.
Since then both teams have injected some fresh blood into the teams, with the likes of Pauline Bourdon and skipper Gaëlle Hermet making an impact for France, while Ellie Kildunne has been a standout for England.
