A sixth try for Wasps! This time its sub Guy Thompson who goes over after a brilliant drive. Joe Simpson converts from the touchline to make it 37-10 with 5 minutes left

Castres on the attack just outside the 22 but again it breaks down, this time its a forward pas so Wasps will have the scrum

Great Masi

From nothing Wasps have their 5th try of the game. After Masi made a half break and oflloaded to Jacobs, Tom Varndell was on hand out wide to receive the pass and sprint over in the corner. Goode strikes the post with a conversion. 30-10 Wasps

Try Wasps!

TRY Castres! It's no more than they deserve so far in this second half. Dumora can't convert so it's now 25-10 Wasps

It has been all Castres so far this half

Max Evans has gone over out wide left but the ref will just check the grounding with the TMO

Castres tap and go quickly from a penalty and burst into the Wasps 22

Hughes picks off the base of the scrum to create an angle for Goode to clear
