Toulouse move was too tempting to resist says Scotland's Richie Gray
The former Glasgow Warriors lock will leave Castres at the end of the season.
Former Glasgow Warriors lock Richie Gray admits he couldn't resist the opportunity to sign for French giants Toulouse.
The 26-year-old Scotland internationalist will join the former European champions at the end of the season when his Castres contract comes to an end.
He's signed a four-year deal with their Top 14 rivals which will see him continue his career in the south of France.
The former Glasgow forward said: "This was a very difficult decision to make, I have loved my time in Castres, the club and the supporters have made my time here very special and I will leave with very fond memories.
"However the opportunity to play for one of Europe's most successful clubs, steeped in history, is an incredible one for me. When I met with the club they described their ambition and I felt this was the right move for me, to challenge myself in what is a very strong squad.
"I still have seven months here at Castres, I will give everything I can to the club in hope of achieving top six and then who knows.
"My goal for now is to leave Castres on the best possible note, I will give everything I can to the club, the players and the coaches."
