Going a goal down after Reinildo Mandava's dismissal, Sunderland earned a point thanks to Wilson Isidor's equaliser.
“It’s a good point against a strong team, especially with 10 men for the majority of the game," said Le Bris.
"We had two different parts in this game. I think we started well 11 against 11, we were in our game plan, and the red card changed the dynamic of the game, but we stayed composed.
“It became a different game with a low block, and it was clear that our main chances would come from set pieces.
“I think especially the first 20 minutes of the second half were well managed.
“The red card was possible. It was, I think, a bad reaction, but in the end, we respect the decision."
Deep block training
He continued: “We were ready because we’ve worked hard on this deep block before, knowing in the Premier League we’ll have to manage this part of the game properly.
“It was good practice today with 10 men - five, three, one - staying organised, managing triangles and crosses.
“On set pieces, we know we have threats from throws or corner kicks, and we were able to score a goal.
“It’s a really good experience, especially here in Sunderland because we have the players, we have the squad, but we also have our fans, our stadium, and the energy.
“We were 10 men, but in fact we were 11 with this crowd.
“We’re happy to be here, but at the same time we have to be competitive, and I think we showed good character.
“Defending deep for a long period is really important because if you can master this phase, you can travel safely.
“It’s always a reset, but at the same time, we can create foundations through these experiences, and this one was really important."
