Excellently read by O'Driscoll.

BOD = Legend

Speculative offload is picked off by O'Driscoll in midfield as the Saints look to go the length of the field. Easy run in from 20 out

Saints steal the LO and are now looking to run it out from deep

Leinster turn it over at the LO and earn a penalty at the ruck. Madigan will go to the line and Leinster will now have an LO on the Saints line

O'Driscoll puts a rather poor kick in behind but it does force Saints to play out from inside their own 22

Leinster on the attack and D'arcy finds a half gap to get over the gainline

Northampton look to get North into the game but the outside backs of Leinster shut them down. Myler chips ahead at the next phase and Clark regathers. Some scrappy stuff at the next phase with Owens ruling the first knock on to come from Saints. Leinster scrum on halfway

Leinster pinged for running the scrum round and Myler will go to the line.

Excellent showing from Cronin
