The two teams face off in Marseille in the Champions Cup Final on Saturday.
Robbie Henshaw hopes the Leinster support can act as a '16th man' in Saturday's Champions Cup final against La Rochelle.
Leinster didn't have fans at last year's semi final between the two sides due to the pandemic, and it was Ronan O'Gara's men who came out on top.
Centre Henshaw says he'll be keeping the head down from the middle of this week, but appreciates the support that will greet the team in Marseille:
