Paul Lambert said Wolves have to cut out errors of both ends of the pitch if they're to get anywhere near Brighton's level.
The Seagulls were comfortable 2-0 winners at Molineux thanks to two goals from Anthony Knockaert.
It was Wolves' second successive defeat and their first at home for four matches.
And Lambert felt it was a deserved win for the visitors, who took the lead when mistakes from Kortney Hause and Andy Lonergan led to Knockaert's opener just before half time.
"I thought we started really well, we looked lively and threatening," he said.
"There was nothing in it up until the goal.
"It's a really poor goal from our point of view, we should have dealt with it on a few occasions.
"You've got to score, that's been the story of our season. You have to take your chances at this level - they've taken ours and we haven't.
"I was disappointed mistakes led to their goals and chances. It's the errors, we've got to cut out errors. Do Brighton make many errors? No, not really.
"We did have chances to score but we never took them. We have to cut out errors at both ends of the pitch.
"The Coady chance was a big one. There wasn't too much between the teams but they were better at both ends."
The likes of Steve Sidwell, Dale Stephens and Glenn Murray all impressed for the Seagulls.
And Lambert believes the experience of Chris Hughton's team puts them a level above Wolves at the moment.
"Brighton are a good, experienced side, well organised with a lot of lads that know the division and have played higher," he added.
"They've got good experience all around and that's something we have to get to, to that level. And not just a one-off, you've got to do that for 46 games.
"We've come up against a really good side who are just about up.
"They sat really deep, they get bodies behind the ball really well and it's difficult to get in behind."
Is experience the key difference between the two teams? "I think experience, know-how and being streetwise," Lambert replied.
"That's a big thing, to be streetwise. They've got it throughout their team."
Donovan Wilson was handed his league debut from the bench after notching nine goals in 10 under-23 appearances.
"He's the one that's been scoring goals in the under-23s, albeit there's a big gap between under-23s and first-team football, but it'll stand him in good stead," Lambert said.
Helder Costa again missed out injured - the third successive game he's missed with an ankle problem.
Lambert said of the Portuguese winger: "Costa was still short, we'll have to see how he is tomorrow and Sunday.
"He's not ruled out for Leeds. I'll wait and see how he progresses."Subscribe to our Newsletter
