Le Bris was happy with their performance after the Falmer stadium stalemate.
He said: “I thought we played well for 65–70 minutes and had opportunities to score.
“We didn’t today, but I think it is always important, when you go away from home against a strong side, to seize those opportunities.
“After that, Brighton pushed, which is normal, and we were a bit on the edge, but it is still a good point.
“Their subs gave them an extra drive, so we had to defend,” he continued.
“It is not easy for the new lads in the squad to step up, but they need time and experience to improve.
“Our centre-backs were very good, as usual, but the squad is always connected to defend together.
“It is not always a question of individual players or centre-backs; it is very much about the collective spirit.”
