The Ospreys will look to earn their first victory in this season's Heineken Cup this evening when they take on Castres away. The Pool 1 strugglers have lost both of their opening European fixtures at home to Leinster and more recently away at Northampton.

Meanwhile Cardiff Blues will also be hoping to lift themselves up from the bottom of Pool 2, when they welcome Glasgow to the Arms Park.

The Blues have enjoyed mixed fortunes in Europe so far, after a 44-29 defeat away at Exeter, before they clinched an historic 19-15 win at home to Heineken Cup holders Toulon.
