In the fifth round of the Top 14, the rugby team from Castres will host Stade Toulouse, the reigning French champion, in a high-stakes derby that has historically favored Toulouse. Despite Castres' modest performance this season, the team has made strategic additions during the off-season and remains undefeated at home. Coach Xavier Sadourny will be looking to turn the tide in a match that could mark a turning point for the team, as they aim to challenge the dominant Toulouse side. The Castres lineup is expected to feature Baptiste Delaporte, who will start in the third line alongside Kyllian Ringuet. Both players have been pivotal in the team's defensive efforts, and Delaporte recently scored a try against Perpignan. The position of number 8, however, remains uncertain. Veresa Ramototabua, who started against Clermont, has struggled to convince the coaching staff, while Abraham Papali'i, who came on later in the match, showed promise. Coach Sadourny may also consider the experienced Scottish player Hamish Watson for the role, which could make this the fourth different number 8 in five matches. Castres has faced a difficult history in matches against Toulouse, with three consecutive losses in recent years. In those games, Castres conceded a total of 153 points while scoring only 43. Their last victory in this derby dates back to October 2024, before Sadourny took over as coach. This upcoming match presents an opportunity for the team to break that losing streak and secure their first victory over Toulouse under their current leadership. The Castres squad has depth, with at least 19 players who have participated in at least three of the first rounds of the Top 14. This experience could be crucial as they aim to challenge Toulouse and change the course of their derby history. With a strong home record and key players in form, the team is hoping to make history on Saturday.
