Leinster v Northampton Saints - All You Need to Know

Familiar territory for Leinster, but not the most familiar location.

It's a 15th Investec Champions Cup semi-final for Leo Cullen's side, with only Toulouse - who play at this stage for the 16th time on Sunday - having been here more.

Semi-finals in the Aviva Stadium have become a near-annual tradition for the four-time champions, but this time they will head north of the Liffey to Croke Park, where an 82,300 sell-out crowd is expected for their showdown with the Northampton Saints.

Leinster have been to Croker once before, defeating Munster 25-6 at GAA HQ back in 2009, but with the Aviva Stadium undergoing prep work ahead of the Europa League final later this month, the province were cleared for a long-awaited return to Drumcondra.

The Saints stand between Leinster and an eighth final appearance, with this game being a repeat of the 2011 decider, which Leinster won 33-22 in Cardiff, having memorably come from 22-6 down at half time.

The winner will book their ticket to London for the final at the Tottenham Hotspur Stadium later this month, where they will face either Toulouse or Harlequins, who meet in the second semi-final on Sunday afternoon.
