Welcome to our Boxing Day coverage of this fixture from the Pro 12. This Welsh derby is important for all kinds of reasons with only a couple of places separating the sides in the table. A win for the Blues could see them leapfrog the champions of two years ago, Glasgow Warriors. Whilst a bonus point victory for the Dragons would see them overtake last years champions Connacht.
