The Champions Cup quarter-finals continue with Clermont hosting Northampton Saints in France. Follow all of the action live!
While Castres, and this season Montpellier, have both won in Clermont, finally ending the 70-game unbeaten home record, it's still been seven years since they lost a European game at home.
In the end it may well come down to whether Northampton can overpower Clermont up front. If they can, they are very hard to stop, but as Racing showed, if Saints can only get parity through their forwards, they are not nearly as dangerous.
