LONDON (Reuters) - Leinster face a Toulon team who usurped them as the kings of Europe in a mouthwatering Champions Cup semi-final clash on Sunday that the Irish side's head coach Matt O'Connor has billed as a "huge challenge".
Big-spenders Toulon, the 2013 and 2014 European champions in the competition's previous guise as the Heineken Cup, take on three-times winners Leinster at the Stade Velodrome in Marseille while Clermont Auvernge play Saracens 24 hours earlier in the other semi at the Geoffroy Guichard stadium in St Etienne.
