Ruben Amorim allegedly damaged the Manchester United dressing room television screen during a furious rant against his Manchester United stars on Sunday.
The United manager had just witnessed his men's 3-1 defeat against Brighton, leaving his team in 13th place in the Premier League.
While gesticulating, the Portuguese accidentally caught the television and it will need to be fixed before the Europa League match against Rangers on Thursday night, according to The Athletic.
Amorim presents himself as a calm figure during his media duties, but this outburst was similar to the cruel reprimands Sir Alex Ferguson would dish out to his stars during his reign.
After Brighton's defeat, now his seventh in 15 games, as many as Steve Cooper when he was sacked by Leicester, Amorim publicly called out his team.
“We are perhaps the worst team in Manchester United's history,” Amorim admitted.

United have lost seven of their 15 games under Amorim and their home record is the worst in 131 years.
'I say this because we have to recognize it and change it. Here you go: your headlines.
“It is unacceptable to lose so many games. For any Premier League club, can you imagine Manchester United?
'The rivals are better than us in many details. I am only here to help my players, but we must understand that we are breaking all the bad records.
“In 10 Premier League games we won two. I know that. Imagine what this is like for a United fan. Imagine what this is for me. We get a new coach who is losing more than the last coach. I am fully aware of it.'
Amorim warned that the worst may be yet to come because he will not change his tactics.
“I knew it was going to be difficult to come up with a completely new idea right now, but when you lose games it becomes really difficult,” he added. 'That's why I tell you that we are going to suffer because I will continue doing the same thing. I'm not going to change, no matter what.'
Amorim also criticized his players for losing discipline and form towards the end of the match.
'Everyone was changing positions and that's something I won't see again. “We can lose but we have to maintain our position,” he said.
“We try to have possession and control the ball, but the players are anxious. This is not acceptable.
They have lost six of their first 12 home league games; The last time they did this was when they were known as Newton Heath.
Jamie Carragher thinks Amorim was “ridiculous” for speaking so harshly about his etam in public
Amorim's team has added only 11 points in the 11 games that Rubén Amorim has directed
'I know we can be successful, but we have to survive this moment. I'm not naive. We need to survive now.”
United have lost six of their 12 home league games, their worst record in 131 years. The last time they reached such a nadir was in the 1893-94 campaign, when the club was known as Newton Heath.
It was also their fourth defeat in their last five games at Old Trafford, and they could well have lost all of those games had Amad Diallo not scored a late hat-trick against Southampton.
Experts have questioned whether Amorim's candid public comments are helpful or detrimental to motivating the team.
Speaking on Sky Sports' Monday Night Football, Jamie Carragher said: “I think it was one of the strangest and most ridiculous things I've ever heard a manager say.” Why would you make a comment like that?
“That's the kind of comment an expert would make and I would have to defend it. I don't know what he gains from that, what the benefit is. We all know it's a poor Manchester United team.
'He just blew something up, a quote that will follow him for the rest of the season. To the reporters he said, 'I've given you your headline.' Why you'd want to do that as a coach, I'll never know.'
“I don't have much sympathy for the players in the Manchester United dressing room, they have been a joke for a few years now.
“A few weeks ago, after playing against Liverpool, there was an interview with Lisandro Martínez where he talked about mentality and touched his head.
“I almost laughed when I saw, to be honest, the number of times Manchester United have basically thrown in the towel with bad performances in the last four or five years.
“From the manager's point of view, how can he go into the dressing room from now until the end of the season and continually strengthen them and give them confidence, if he says they are one of the worst teams in Manchester United's history?
“I would be very surprised if the powers that be above him didn't have a strong word with him. You can't talk like that as a Manchester United coach. “You don't add gasoline to the fire.”
