The result marks the longest unbeaten home run by a newly promoted Premier League side since 1992-93, keeps Sunderland seventh in the table and moves them onto 29 points from 19 games.
Le Bris said afterwards: “It was a good game against a really strong opponent, probably one of the best in Europe.
“It was important to defend properly and I think we showed we were able to defend high and also with a mid-block.
“When they stepped up with their quality and managed the ball in our final third, they showed they could create many chances.
“Our character was good and even when we were on the edge, we always had a head or a foot to protect the goal. That was important tonight.
“It was also important to escape their counter-press. In the first game a few weeks ago they were excellent and it was absolutely impossible to get out, but today we did well and our build-up was better.
“We are growing and learning from different experiences.
“The standards within our team are high. We want to get better and it is important to always have that mindset, because if you want to stay at the same level, you will be punished.
“We must be ambitious and hopefully that will be the case in our next game.”
