Ruben Amorim has said his Manchester United team might be the worst in the club's history following their 3-1 defeat to Brighton & Hove Albion on Sunday.
United failed to register a shot on target in open play as Brighton dominated at Old Trafford.
The result means Amorim has already suffered four home Premier League defeats since taking over as manager from Erik ten Hag, who was sacked at the end of October.
"We are getting a new coach who is losing more than the last coach," Amorim said. "I have full knowledge of that. I am not going to change, no matter what.
"I know we can succeed but we need to survive this moment. I am not naive. We need to survive now. We are the worst team, maybe, in the history of Manchester United.
"I know you want headlines but I am saying that because we have to acknowledge that and to change that. Here you go: your headlines."
After two positive results against Liverpool and Arsenal, Amorim said he would learn more about his players during the games against Southampton and Brighton.
United survived a huge scare against Southampton, the Premier League's bottom team, before winning 3-1 but were comprehensively beaten by Brighton.
Amorim has now lost seven of his 15 games since being appointed. United are 13th in the table, five places and 10 points above the relegation places.
"Everybody here is underperforming, no matter what the circumstances, we are underperforming and have to accept that," Amorim said.
"It's unacceptable to lose so many games. For any Premier League club, imagine Manchester United. So it's a really hard moment but we have to continue, we have to continue, there is no other way. We need to suffer and continue."
