'Something's broken' - Wayne Rooney admits worry over Ruben Amorim's 'damning' message to Manchester United players after Grimsby catastrophe

Manchester United's all-time top scorer Rooney has raised alarm bells over the state of his former club, claiming "something's broken" after head coach Amorim’s post-match comments following the Red Devils' shock Carabao Cup defeat to League Two minnows Grimsby Town earlier this week.

Following the second round defeat, Amorim didn't mince his words and suggested that his side did not play as a team. "I know that the best team won. The only team that was on the pitch," said the manager. "The best players lost. Any team can win against a group of players. I think that the team and the players spoke really loud today. That’s it. We lost, the best team won. It’s not just the space [Manchester United gave Grimsby], but the way we started the game without any intensity. All of the ideas about the pressure, we were completely lost. It is hard to explain."

There has been growing speculation that the former Sporting CP boss could resign from his role at Old Trafford if he doesn't produce an immediate turnaround in fortunes, despite reports that he retains backing from the United hierarchy.

Speaking on BBC's The Wayne Rooney Show, Rooney said: “The biggest concern is the manager’s words after the game were damning on the players. Being in a position where I've been in that dressing room, if your manager comes out with those words, there’s something broken.

“There's something not right. That's clear. The manager said that after the game and that's clear for everyone to see. Even though it's only three games into the season it's getting to a point where it's like, ‘what is going on?’

“The problem we've got now is who would want to take it [manager's job]? Which is crazy to say. You've got one of the biggest clubs in the world and you're probably just sitting there thinking... not now.

“We forget he's 40, he's a young manager. Manchester United is so different to where he's been before. There's the media team, the commercial team, the fans, it's completely different. There's a pressure with United which he will never have felt before. When you're not winning games, that starts to get to you. It looks like this was a breaking point for him.”

Amorim will be hoping and praying for United's first win of the season when they take on newly-promoted Burnley at Old Trafford on Saturday.
