It wasn’t a vintage performance but Matt O’Connor’s side are now two for two.
Leinster completed a 21-16 win over Castres thanks entirely to the boot of Ian Madigan.
Madigan’s seven penalties were responsible for all of Leinster’s points, as they overcame a spirited Castres side that was not able to build upon Saimone Taumoepeau’s early try and keep their Irish opponents at bay.
