Hello and Welcome to Ultimate Rugby's coverage of this afternoons Top 14 semi-final between Castres and Montpellier live from from the Stade Pierre Mauroy. We have a grudge match on our hands today as these two teams played eachother in the 2011 play offs, Montpellier coming out on top in that occassion so definitely a chip on the Castres Olympique shoulder about that one. Castres are on a massive high after causing one of the upsets of the decade last weekend as they ended Clermont's unbeaten streak at home, coming out 22-16 winners. Castres do have a bit of mental advantage as well as they have won both of the regular season meetings between these two sides. Montpellier are also coming off a good win as they beat other semi-finalists Racing Metro 44-10. However Racing were the inferior side last night as they lost to Toulon 16-6 so a huge task for whoever comes out on top today. That will be decided over the next 80 minutes or so and kick off is just minutes away!
