Imanol Harinordoquy has said that France must step up their game if they are to beat Ireland in the Six Nations this weekend.

France host Ireland at the Stade de France on Sunday after their original February 11 fixture was postponed due to a frozen pitch.

Though they have beaten Scotland and Italy so far, the loose forward believes that France must improve to make it three wins in a row.

"Defensively we saw what was good and what was less so," Harinordoquy said.

"Offensively, we were a bit all over the place launching solo raids without taking into account a more orderly approach to counter-attacking and we were a bit disorganised.

"The players, including myself, sometimes took too long to follow the man with the ball and provide some impetus behind him. It is imperative we correct that."

France are currently second in the Six Nations table.
