The Dragons welcome Cardiff to Rodney Parade on Boxing Day today, with the eye instantly drawn to the battle between two stellar Welsh No. 8s. Taulupe Faletau lines up for the Blue and Blacks against his old side, who have current Wales No. 8 Aaon Wainwright to call upon. It promises to be a fascinating battle, with both likely to feature in Warren Gatland's Six Nations squad. There's naturally, as there often is in Welsh derbies, plenty of intriguing battles from position to position, while there's also extra bragging rights at Christmas. Kick-off is at 5.15pm and the match is being broadcast on S4C.
