Welcome to our coverage of the first Welsh derby of the season here at Liberty Stadium between the Ospreys and Cardiff Blues. This one is a top of the table clash as the sides are placed in 4th and 5th place respectively. Ospreys had a fantastic start to the season but have since lost two on the bounce. Cardiff also come off of a loss, at home to Leinster last weekend. Both teams will be looking to get their seasons back on track with a victory over their rivals tonight.

Cardiff should cut it close
