Good evening and welcome to this crucial final round pool 1 game from Franklins Gardens. Hosts Northampton take on travelling Castres and are in need of a big win as they currently sit four points adrift of leaders Leinster who welcome the Ospreys tonight. French champions Castres let an early lead slip last week at home to the Irish side and as such have little to play for but pride tonight. The reverse of this fixture was all the way back in round 1 with Castres being the victors on that occasion, winning out on a scoreline of 19-13. Despite their Heineken Cup aspirations being over for the season, Castres have brought a strong team to England. They are clearly intent on competing so this promises to be an exciting contest, be sure to stay tuned.
