Speaking to BT Sport, La Rochelle head coach Ronan O'Gara said: "It's a great performance because we never gave in mentally. Saracens have a great mindset and are founded on doggedness and respect and we knew we would be tested.
"We never put them away but the game was based on fine margins. What was pleasing was that we didn't give them scores. We are very happy. It's a special place and it's important for me as a coach to connect with the boys and we represent the town well."
