Enzo Le Fée’s penalty, Bertrand Traoré and Brian Brobbey struck the goals for Sunderland on Saturday.
Le Bris said afterwards: “To come from two-nil down and win this game is a big achievement.
“It shows once again that this team has a strong character - they are never beaten and they want to fight. Many teams would give up after going two down, but that wasn’t the case for us today.
“This league is really demanding. You make two mistakes and you are punished both times very quickly.
“We were disappointed because I thought we started well with the ball. We felt their threat on our right side especially - we tried to manage it, but they were good.
“It was important to be clinical in the box, and we were. It was just a case of trying to change the dynamic, and we did it. We have great energy in the stands. If we give a lot on the pitch, they will react. The weather was nice this afternoon, we created a special atmosphere, and we were able to win the game.
“We don’t know what we can achieve this season. It’s important to play each game as it comes - last weekend we lost at Fulham and were dominated. We changed the dynamic this weekend. We reset and we go again.”
