The two teams last met in December 2017, with Sunderland winning 1-0 in the Championship. Sunderland is currently in seventh place with eight points and has not lost in their last three Premier League matches.
Le Bris talked about midfielder Habib Diarra, who will be out until December and may miss the Africa Cup of Nations in January. He emphasized the importance of allowing Diarra to fully recover from his injury without rushing the process, as he is a young player.
Le Bris also noted that injuries can provide opportunities for other players to step up and show their abilities, and that the team's depth is still a work in progress.
He described Forest as a "strong squad with many threats" and warned that they will not give Sunderland any easy wins.
Le Bris praised Chris Rigg, who played well in the Championship last season and has been working hard to adapt to the Premier League.
Le Bris acknowledged that Postecoglou will need time to adapt to his new team, citing the coach's proactive and offensive style and the talented players at his disposal.
When asked about the value of signings Nordi Mukiele and Omar Alderete, Le Bris emphasized that price is not always a measure of a player's quality, and that these two players have shown consistent performances on the pitch.
