ASM Clermont Auvergne’s European Rugby Challenge Cup semi-final against Harlequins at Stade Marcel-Michelin on April 20 will be their fourth home semi-final in the competition. To date, they have won them all, including two as Montferrand. 1999 - Montferrand 27 Narbonne 21 Montferrand staged an excellent fightback in the second half to reach their first European Challenge Cup final. Trailing 14-12 at the break, they ended Narbonne’s seven-match winning run in the competition with a thrilling rally and went on to win the trophy by beating Bourgoin 35-16 in the final. 2004 - Montferrand 38 Bath Rugby 22 These were the days when the Challenge Cup semi-finals were decided over two legs and Montferrand squeezed through to the final by just two points after losing the first leg 29-15 at Bath. Montferrand virtually sealed their passage in the first 20 minutes, when they overturned their first-leg deficit after converted tries from Tony Marsh and Pierre Mignoni, before marching into a 28-3 half-time lead following a further score from Marsh. A fourth home try from Olivier Magne in the 50th minute seemed to herald a rout, but two quick yellow cards allowed Bath the chance to strike back with tries from Zack Fe’aunati and Simon Danielli before a late score from Wylie Human left home fans anxiously awaiting the final whistle. 2007 - ASM Clermont Auvergne 46 Newport Gwent Dragons 29 Clermont eased into their third Challenge Cup final by edging a try feast 6-5, but never looking like losing after Brock James had put them ahead with two early penalties. The veteran Australian fly-half then converted five of Clermont’s six tries, which came via Aurelien Rougerie, Gonzalo Longo, Thomas Domingo, Tony Marsh, Brice Miguel and Pierre Mignoni. Two tries from Aled Brew and one apiece from Adam Black, Ian Gough and Phil Dollman, plus two conversions from Ceri Sweeney, kept Dragons’ pride intact, but it was Clermont who sealed a final clash with Bath Rugby, which they went on to win.
