Life left in the Pro12 teams in Europe
What a difference a year can make in sport. This time last year, the Guinness Pro12 teams looked to be on the back foot in Europe, and the English and French were streaking clear in the Champions Cup.
Money was a huge factor surrounding the new lay-out of Europe's top club competition, and the Premiership and Top 14 clubs looked set to dominate indefinitely.
But now the Pro12 clubs are back in form, and once again the Irish have cracked the code and risen to the top of the pecking order, with two teams in the last four - Munster and Leinster.
They both claimed brilliant victories over former champions last weekend, with Munster hammering Toulouse 41-16 at Thomond Park, and Leinster impressing in their 32-17 success against Wasps.
There were no Pro12 teams in the last eight last season, but Glasgow had the chance to make it three teams from four in the semi-finals had they got the better of reigning champions Saracens.
It shows how strong the structures are in Ireland, but that could be under threat because of the success, with Donnacha Ryan and Pat Lam going, and now even Rassie Erasmus is under threat too.
