The decisive moment came in the first half when Omar Alderete powered home Granit Xhaka’s free-kick, awarded after Nicolas Domínguez was penalised for diving in a challenge with Trai Hume.
Ultimately, the Black Cats held firm to secure a valuable three points, earning their third clean sheet in six league games.
“It was good to win because it wasn’t an easy challenge,” Le Bris told Sunderland website.
“It was our first away win in the league, so I’m really proud of our fans and our squad because we worked hard.
“They have many threats and are really good on the ball.
“After we scored the first goal, their substitutions added five more attackers, but we expected that. We defended well with the back five.
“The players were really well connected, they worked hard, and we had a good goalkeeper.
“If you defend with an open block, they will punish you. We expected to be a bit more comfortable or confident at times.
“We can’t always manage the situation with only 11 players. Last week we had to change the game plan after 35 minutes, and it was the same today.”
