Ruben Amorim stressed that Manchester United must adopt survival mode after a fourth defeat in five Premier League games.
United were stunned at Molineux by a resurgent Wolves who scored twice in the second half to make it two wins from two, with Matheus Cunha and Hwang Hee-chan scoring.
However, it was a sobering defeat for the visitors, who have now lost each of their last three matches, conceding nine goals in the process, as the Amorim era encounters its first hurdle on the road to restoration.
Asked if his team should worry about the bottom teams, with United 14th in the Premier League and just seven points clear of relegation, Amorim said: “Yes, at the moment we just have to survive and win sometimes.” .
Amorim, who has lost five of his ten games in all competitions as United manager, added that United must forget about qualifying for European football next season.
“No, no, no, no,” he said when asked if United could think about Europe. “We have to work on many things at our club, both on and off the field.”
Rubén Amorim's team has lost five of its 10 games since the new coach took over
The Red Devils coach admitted that his team needs to start worrying about the teams below them.
Bruno Fernandes was sent off just after the break, and Wolves took the lead soon after.
Perhaps even more alarming for United fans, Amorim insisted he has “no idea” how long it will take for his team to improve.
'I have no idea. No idea,' Amorim said. “Instead of trying to understand how long it will take, day by day it's about improving, trying to watch videos and use every minute of training and try to earn some points because it's really important right now.”
'The idea needs time. “This will be a difficult moment, we are far from the end of this moment and that's it, we have to continue and focus on the next game.”
With the score still tied at 0-0, United had as poor a start to the second half as they could have hoped for.
United captain Bruno Fernandes was sent off in the 47th minute for a second booking and, for the second time in three games, Amorim's team awarded a corner directly.
Cunha's shot beat Andre Onana, sliding under the bar, before Hwang sealed the game for Wolves in stoppage time, converting back into goal to seal a huge three points for the hosts.
Vitor Pereira, who has won his first two games in charge of Wolves since Gary O'Neil was sacked, revealed Cunha had worked in the corner in training.
“He (Cunha) is a top-level player,” Pereira said. “He is a special player who can do things that make a difference in the small details. We tried this corner that swings in to exploit it. With these types of players, these things can happen.”
Vitor Pereira admitted that Matheus Cunha's corner goal was something he worked on
While Man United's form is faltering, Wolves have made it two wins from two under Pereira.
Hwang Hee-chan secured the three points at the end of the game with a close-range shot.
The forward himself added: 'I feel very happy. We didn't start the season well, we came together, we suffered together and we scored together.
'You can see how happy the fans are. He (Pereira) came here with a lot of energy and said his dream was to come here and manage a team in the Premier League, and you can see the energy.
“We trained him a lot, we tried to control the goalkeeper and we did it very well and I am very happy.” The first part I made one and it was saved and in the second part I have some luck.
“Channy tells me every day 'pass to me and I'll score' and I'm very happy because I had the opportunity to pass to him and he scored.”
As Amorim leaves Molineux already thinking about how he can improve his team when they face Newcastle on Monday, his counterpart Pereira admitted it was “special” to win his first game at his new home.
'It's a fantastic and special feeling. We can see that the players are willing to suffer and compete for each other.”
