Ruben Amorim reportedly smashed a television in the Old Trafford dressing room in a furious rant at his squad after Manchester United’s 3-1 defeat against Brighton on Sunday.

The result was a seventh defeat in 15 games for Amorim, who succeeded Erik ten Hag in November, and a fourth reverse in the side’s past five home Premier League games.

Amorim, who afterwards labelled his side “the worst team maybe in the history of Manchester United”, was reported by the Athletic to have been gesticulating angrily in the home dressing room when he ­damaged the television, which is used for pre‑match tactics and needed ­repair in time for the Europa League game against Rangers on Thursday.

He had calmed down before he spoke to the media on Sunday, although he pulled no punches in the assessment of his team as they slipped to 13th in the Premier League table.

“It’s unacceptable to lose so many games,” he said. “For any Premier League club, so imagine ­Manchester United? The opponents are better than us in many details. I am just here to help my ­players, but we need to understand we are ­breaking all the bad records.

“In 10 games in the Premier League, we won two. I know that. Imagine what this is for a United fan. Imagine what this is for me. We are getting a new coach who is losing more than the last coach. I have full knowledge of that.”

Amorim, who had four and a half successful years at Sporting where he won two league titles before arriving at United, has had the reputation of being a calm coach who rarely conducts post-match ­dressings‑down of his squad.

However, he seemed particularly annoyed with the way his side finished the game on Sunday when a mistake by André Onana handed Brighton a third goal on 77 minutes, and any hopes of ­repeating the late recovery from their previous game against Southampton were dashed.

“Everybody was changing ­position and that is something I will not see again. We can lose but we have to maintain position,” he said after the game. “We try to have possession and control the ball, but the players are anxious. This is not acceptable.”
