Vicente Guaita was called into action as the game wore on after Edouard took the lead in the 38th-minute.
Reflecting on the match with the media, Edouard said: “It was a strange game because we started well in the first-half and managed to score but the second-half was more difficult. Southampton pushed a lot but at the end we win the game.
“I think deserved the win because we managed to score first, managed to keep a clean sheet and so we deserved the win.”
