Full coverage: Leinster

Ireland's season has exposed cracks in depth, cohesion and succession planning, but Andy Farrell's side arrives at Eden Park with one final chance to prove those problems are fixable rather than fundamental.

The trophies are already secured. The lasting verdict on Cullen's reign may depend on whether Leinster can emerge from his shadow without suffering the effects of authority decay.

Nienaber against McNamara is the most fascinating coaching subplot of the weekend. The contest that decides the game might well be the one between the South African defensive engineer and the Clare man with the maths degree.

Leinster’s win over Toulon was decisive for long stretches, yet Leo Cullen’s post-match rhetoric and a messy finish ensured the performance sparked more questions than it answered.

Leinster have the strongest squad remaining in this competition. With an international in every position, this is a group of players that should be targeting a club double. With the talent available to Cullen and Nienaber, that is a realistic ambition, not a fanciful one.

Leinster's climbers are starting to find their legs again after taking a different route map to the European glory that has eluded them for too long. Leo Cullen's men should have too much for Edinburgh, but can they at last conquer their Everest again?

Leinster return to Croke Park with more than a title on the line. After weeks of criticism and tactical soul-searching, only one thing matters now: perform, or prepare for the fallout.

Despite elite resources, world-class coaching, and a production line of international talent, Leinster Rugby’s repeated failures in Europe’s biggest competition reveal uncomfortable truths.

Munster will look to employ a kicking game to disrupt Leinster's defensive rhythm, followed by clever short-side attacks off lineouts, designed to counteract Leinster's aggressive blitz defence. Will it be enough?

Connacht are in re-build mode. Leinster are looking for redemption. Munster are looking to rebuild, while Ulster are in transition. Despite all that, the chances of an Irish team winning the URC remain strong.
