Sunderland are beginning arguably their most challenging spell of the Premier League season

Régis Le Bris says he believes he has the depth in his squad to cope as six senior players depart to represent their nation in the Africa Cup of Nations.

Chemsdine Talbi, Habib Diarra, Arthur Masuaku, Noah Sadiki, Bertrand Traoré and Reinildo will all play in the tournament, and could be absent for a month if their nations progress ot the latter stages. Simon Adingra's absence from the Ivory Coast squad does give Le Bris an unexpected option during a busy period of the campaign, but the competition is set to provide a major test of Sunderland's squad depth.

Le Bris says he backs those who have been waiting for their opportunity to step up, and believes the confidence that has been built in the group through the opening weeks of the season could be key.

"First of all, we wish them the best because I think it's really important for them to play with their national teams," Le Bris said.

"I think we still have a strong core in this group with great experience, good confidence at the minute, 26 points, which is useful for the next fixtures. After that, some of the players didn't play a lot and they will have opportunities to show their qualities. I believe that we have good players right now on the bench and they will show that they can help the squad."

Brighton will miss influential midfielder Carlos Baleba this weekend as he represents Cameroon, but he is their only absentee as a result of the competition.

Régis Le Bris praises unity of Sunderland squad

Sunderland's narrow win in the Wear-Tyne derby was further evidence of the togetherness in the squad, which could be vital in the coming weeks as the club face arguably their toughest test yet since winning promotion.

"Yes, I think we showed our progress," Le Bris said.

"I think it's not only me, it's not only one player. It's about a collective project, teamwork. I think it's one of the main strengths of this club. We are working together. The players are showing on the pitch that these connections are probably the main strength of the squad, whether in possession or out of possession. I think it's already the case. It's also the case for the club and for the different staff."
