Head Coach Steve Tandy said:
"This is the first game of a busy five weeks with three big derbies followed by the final two rounds of the Heineken Cup. Christmas is a great time for rugby, with fans to come together with family and friends to watch the game. It's about the tradition and the rivalry and it's fantastic for regional rugby in Wales that we are going to have a series of games with big crowds and great atmospheres.
"We are looking to build some momentum after showing some good signs in the games against Castres, where we started to see the boys taking what we've been doing in training onto the pitch. The win last weekend was a great result for everybody involved with the region, but there is still plenty of room for improvement. The boys have worked hard in training this week, striving to continue improving, in preparation for what will be a busy period.
"It's important that we are at our best in Cardiff in front of a big and passionate crowd. We know there'll be a large travelling support there from Ospreylia, enjoying the rivalry, and we want them to be proud of what this group is doing.
"If we can keep the momentum going and put in the kind of performance they expect, we'll be in a good place before back to back games against the Scarlets. It's always tough if you have two away games on the bounce, but we'll be happy to bring them back to the Liberty for the second game in front of a big crowd predominantly made up of our own fans passionately supporting the cause."
