Dan Biggar gets us under way. Immediately Castres look to threaten

Hello and welcome to Ultimate Rugby's coverage of the first game of round 4 of the Heineken Cup. This fixture, a reverse of last weekend's game, sees Ospreys play host to Castres. Last week the Top 14 champions were run close by the Welsh visitors but in the end the boot of Rory Kockott proved the decisive difference. Castres have made a number of changes this week with Geoffrey Palis coming in for Dulin, Remi Tales returning to fly half and a new look back row includes Antonie Claassen at 8.
Ospreys are without a win so far in the group stages but will take heart from their losing bonus point last week and in front of their own fans, no doubt they will fancy their chances.
KO to come in 10 minutes, stay tune for live updates.
