Wolves boss Nuno lamented their second-half collapse for Saturday's 3-3 draw with Brighton.
Nuno said Brighton's penalty straight after half-time changed everything at the Amex Stadium on Saturday and mistakes need to be cut out by Wolves.
The penalty allowed Brighton back into the contest in East Sussex, after Wolves had looked comfortable at 3-1 up at the break.
The manager said, “It was mistakes. After a fantastic first-half, from the first minute of the second-half there's no explanation for it. It was the first action of the second-half, it's what changes the game as a whole.
“The first-half, every time we attacked, we were dangerous, caused problems, controlled the game well. I felt the game was in our control.
“It's just a question of sticking together, do what we have to do, control the game, and I think the team has enough ability to do much better. It's a mistake of the team.
“We have to be much more responsible, knowing Brighton are going to react. We will go, try to analyse the mistake and correct it, but we are frustrated about it."
On his young team, Nuno added: “We didn't plan it, but it happens, we have to react to it. Players need time to develop, but the chance is there, so now we have to react, not panic.
“Fabio [Silva] is getting used to it, it's a very physical game the Premier League, he did a fantastic job against big centre halves, I'm proud of that. He has to grow, and this process has to speed up."
