Wales captain Martyn Williams admitted France simply had too much quality for his side to deal with at the Stade de France on Saturday.

The 33-5 defeat in Paris consigned Wales to a RBS Six Nations whitewash and the dreaded wooden spoon.
The visitors made a promising start with a sixth minute Gareth Thomas try, but the French enjoyed a complete dominance from then on.
Williams, who was easily Wales' most outstanding performer over the five games, had nothing but admiration for the French side.
"We are very disappointed," he told BBC Sport after the final whistle.
"When we went 5-0 up and then Craig (Morgan) went close - it could have set us up for a very good start.
"Unfortunately they are very good side and you've got to give good credit to them.
"They kept the ball, kept territory and kept us down in our 22.
"We made a lot of mistakes that let them back into the game. A missed lineout here and a missed kicks into touch.

"But full credit to them they are a very tough side and they deserve to win."
Despite slumping to a first ever winless Six Nations campaign, Williams feels the side is improving.
"We put a couple of good performances against Ireland and England. We're going forward as a group.
"A bit of patience with the squad and the team will come together for the World Cup.
"We showed last week we can compete with the best."
Coach Steve Hansen will undoubtedly come under pressure from a critical Welsh public and media.
But Williams stressed Hansen is the right man to take Wales to the World Cup next autumn.
"He's done a great job," Williams insisted.
