Leeds boss Jesse Marsch felt they failed to create enough chances in defeat at Leeds.
Brighton won 1-0 thanks to Pascal Gross' winner.
Marsch said: "First half I thought Brighton was much more on top of the game, forcing mistakes on us and making it difficult but second half I thought it was different. Second half I thought we pushed them more. We played more in their end.
"We were not creating as many clear chances as I would have liked us to but certainly we were we changed the way we played. We changed our strategy, and we push the game more. Maybe Luis' goal goes in or we have another little bit of a moment where we're a little bit cleaner and clearer when we're in the box and we make a final action, we get the lead and maybe the feeling in the game is totally different. One thing we know, after Chelsea there was a lot of fanfare on the performance but what this league is every match is a little different.
"Every opponent is a little different but every opponent is very good. I think that Brighton, certainly in the first half, really strategically managed the match much better than we did and then made it difficult for us to find the game at all, but I thought second half, again, that we did okay."
