"We have got a lot to prove now after the last couple of games and I'm looking forward to it.
"There were a lot of things in the papers about a lot of opportunities that went astray against Scotland but on a different day we could have scored three tries and finished them off, unfortunately we didn't but it's only small tweaks for the France game.

"France are a wounded animal having lost three games in a row, a lot of pride is at stake for both teams, it's a mouth-watering game."
