Wilson said, "We are expecting an unbelievable atmosphere in Clermont Ferrand with reports of over 10 000 tickets sold already. I went there earlier in the season with the Scarlets and have told the players what to expect. It will be like a Heineken Cup game out there, something most of the players would not have experienced before but an experience for them to enjoy and learn a great deal from.
"Consistency is the name of the game at this stage in the tournament. We missed a few attacking opportunities against Ireland last weekend but some of the positives include the strength of character we showed in digging in for the win and our scrum.
"France have a lot of first class experience within their squad and I'm sure they will be determined to put in a polished performance in front of their home crowd. We showed glimpses of what we are capable of on Friday night but we are going to need to demonstrate a mature ability to mix things up between playing a tight game and opening things up when the opportunities arise.
"Jack Jones did very well after being brought into the starting line-up but Carwyn was selected to start and deserves an opportunity this weekend."
