Graham Potter thought Brighton controlled the game as much as they could against Crystal Palace, but faltered in dealing with the atmosphere.
Wilfried Zaha’s goal in the 76th minute denied the visitors three points in the M23 derby, a game in which they had the lion’s share of possession and shots on target.
Neal Maupay had fired them ahead early in the second half, but they failed to hold on for the win.
“The performance was really, really good,” Seagulls boss Potter told Sky Sports. “Apart from five minutes I thought we were in control and played well. We put a lot in and there was a lot of good stuff there.
“They had hardly anything in the first half and then in the end it was a bit chaotic. You can’t control a game away from home much more than that. I don’t remember them having too many chances.
“We know if there is one action from a really good player you can be punished.
“Our job is to accumulate points but knowing the competition is really fierce. We try to improve and see where that takes us. Nothing is easy but we just have to keep working.”
Elaborating to BBC Sport, Potter added: “I’m proud of the players.
“We could always look to improve and do something better but you have to hold your hands up to the quality of the strike. They were putting balls into the box and we could have dealt with that better. But we created a lot of opportunities. Lots to take forwards in a positive way.
“In the Premier League you know if you don’t get a second goal – and the home crowd get behind the team – the environment changes.
“We dealt with it OK but not well enough because they scored. [Apart from] a second or third goal and keep a clean sheet, we haven’t done too much wrong. They have good footballers. We kept them as quiet as we could but not enough.
“Neal Maupay scored a really good goal. He worked hard and did his job for the team. It’s nice for him to be among the goals.”
