Today’s game at Thomond Park will be the 15th meeting between Munster and Castres, more times than any other clubs have met since the beginning of European Rugby’s top competition.
Johann van Graan’s side is unbeaten in the last six games between these two sides, with 5 wins and a draw.
Munster’s 45-point victory over Castres Olympique in Round 6 of last season’s Heineken Champions Cup was the southern province’s biggest winning margin against a Top14 side.
Castres, who defeated Gallagher Premiership side Exeter Chiefs in the previous round, are seeking their first back-to-back wins in the competition since the pool stages of the 2012-13 season when they won three consecutive games.
Munster have won their last 10 Champions Cup games played at Thomond Park and have achieved four-try bonus point wins in three of those games in the pool stages.
Castres have a poor record against Irish sides, having won just four of their previous 24 games against Irish opposition, with all four of those wins coming on French soil.
Johann van Graan’s side have conceded only 20 turnovers so far in the Champions Cup this season, the fewest of all teams competing in the competition. They have also won 17 turnovers, which is the joint highest in this year’s Heineken Champions Cup.
On the negative side for Munster, the team has conceded more penalties than any other team in the completion this year, with 27.
Castres’ forward Steve Mafi has beaten 10 defenders from 6 carries in the three rounds played in this year’s completion, more than any other player.
