Sunderland were beaten 2-0 on Saturday despite Brighton being reduced to ten men early in the second half
Régis Le Bris says he is confident his Sunderland side will turn the tide after falling to their third Premier League defeat in a row against Brighton.
The Black Cats struggled to create chances in a frustrating end to the game after Pascal Struijk was shown a red card shortly after Maxim De Cuyper's opening goal, and ultimately fell to a 2-0 defeat after the visitors scored on the break in stoppage time.

Le Bris was frustrated with his side's struggles in the final third in particular but is confident that his team can manage the demanding schedule ahead of them this season.
"You can't build in one day a team who can manage many different scenarios, many different situations," Le Bris said.
"We are in this process, and we have to stay humble.
"We will struggle at times, and it's part of the process. Brighton struggled at times before [after promotion], but they are in a good run and they have built momentum. We were just on the edge today so we have to keep the personality, keep improving, keep learning, stay positive, trust your process, and we'll change the dynamic."
"We are disappointed, clearly," he added.

"But we earned this challenge last season, and we are proud to be in this situation.
"It's tough, and the personality, the level in this league shows that when it's that moment, when it's easy, you fly, everything is easy, no problem. When it's tough, you see the level of your squad, you see how you manage different situations, and it's going to be the case for us now so l'm looking forward to it."
