Castres loom large on horizon for Blues

Leinster 9 Northampton 18

It is four years ago this week since Leinster played Castres on their home ground for the first and only time and it is more than the memories of the bone-chilling temperatures which will send shivers down spines at the thoughts of returning.

Leinster had travelled on the back of a convincing 33-10 win at the RDS — albeit one that left the fifth bonus point behind — knowing their hosts were in anything but the optimal sort of shape to spring a surprise.
