Sunderland earned a comfortable 3-1 win away at Everton on Sunday (May 17), moving them into ninth, one points off a Conference League spot.
Le Bris’ side have just one Premier League game to go this season, hosting Chelsea, who are also desperate to qualify for Europe.
Speaking to Sky Sports after the game, Le Bris admitted that his side “are becoming ambitious” with continental football in their sights.
"The first half was OK, not bad, but we didn't threaten he opponent's defence enough and conceded a goal on a set piece,” he said.
“Second half more ambitious, taking more risks and the subs helped. It was the most important statement at this stage in the season, that the group is still a unit.
“It's never easy, two games before the end to keep everyone aligned but this was the case. So I'm really pleased by the subs as well.
"We are becoming ambitious. It's reality now because we have one more game and we have the opportunity to achieve something really special. Now it's just a final and we'll see.
"It's the club and the team, the staff and the direction we are really well-aligned. It makes a difference at the end so I'm proud of that.
"Our fans were loud today so I imagine they will be louder next week. They deserve it, they are always really supportive. We have highs and lows and they were still behind us. I hope that we can enjoy the last fixture at home."
Message to players before next week? "Consistency, standards and ready to be competitive. You have to manage the expected and also the unexpected.
“If you are ready and prepare well you give yourself the best chance to be successful. Consistency, teamwork and connections."
