Referee having a word with both captains over a few niggles off the ball, its clear both teams are fired up.

We're off!

Good evening and welcome to UR's coverage of Clermont and Castres. This top of the table clash looks like some encounter. Clermont are fresh off a good win last weekend against the Leicester Tigers. Castres on the other hand had the week off and their form as of late has slipped. Last time out they only managed a draw with bottom side Biarritz and before that they went down 25-10 to a Jonny Sexton inspired Racing Metro. However the visitors are still in strong contention for the Top14 and a win tonight of more than 12 points would see them to the top of the table. Clermont though are a formidable force, especially at home. A win this evening would also send them to the top. Just 7 minutes till KO.
