With a new coaching team set to take Wales into the Six Nation the festive derbies have never taken on such importance, and one player who will have more of a point to prove than most is Cardiff openside Thomas Young.
He has recovered from injury to start for the Blue and Blacks in their Boxing Day clash with Dragons RFC at Rodney Parade (2.15pm kick-off).
Openside flanker is the most hotly contested position in Wales with the likes of Justin Tipuric, Jac Morgan, Taine Basham, Tommy Reffell and Josh Macleod all in the frame, but no player this season has been in better form than Young who has been a revelation since re-joining Cardiff from Wasps.
