Leinster currently attacking inside Castres half. Good line from Sean O'Brien but he's lost it at the ruck and Castres clear down the field.

Castres have a chance to get 3 points back after Leinster were penalised for being offside but Kockott's effort drags wide. Still 9-0 after 20 minutes.

Mistake from Castres at the scrum and Leinster have a chance to extend their lead, which they do and Leinster lead 9-0. Good start by the home side.

Castres scrum comes to nothing and Gopperth clears, which Brice Dulin knocks on and now Leinster have a scrum outside the Castres 22.

Great kick from Kockott as he gets the right bounce and gives Leinster a lineout deep inside their 22. Which they knock on and Castres have a scrum.

Great kick from Jimmy Gopperth from about 45 metres out to take Leinster in to a 6 point lead after 12 minutes.

Unlucky for Leinster! Cross kick from Gopperth and Rob Kearney with a lovely bit of skill toe pokes it beyond the defender but can't get away from the Castres defence. Castes then with their own attack look dangerous but at the right time Isaac Boss comes in to clear the ball. Still 3-0.

Both teams just settling into to the game. Leinster have had more of the ball.

He gets his kick and Leinster lead 3-0 after 3 minutes.

Good start by Leinster as they win an early penalty right in front of the posts. Jimmy Gopperth looking to start the game with 3 points.
