Bruno Guimaraes revealed strong words were spoken in Newcastle United’s dressing room after the defeat to Manchester City.

Bruno Guimaraes pulled no punches when assessing Newcastle United’s 4-0 defeat at Manchester City, using words like “lazy” and “shambles”.

Omar Marmoush scored a hat-trick in 14 first-half minutes before substitute James McAtee added a fourth during the closing stages. When asked what went wrong, Guimaraes, Newcastle’s captain, said: “Everything, from my point of view.”

Eddie Howe set up his players to press Man City but never recovered once Marmoush broke the deadlock in the 19th minute after Ederson’s long ball forward was misjudged by Kieran Trippier.

The Egyptian - a £59million January signing from Eintracht Frankfurt - scored a second from the edge of the box before completing his hat-trick by turning home Savinho’s cross.

Strong words were said in Newcastle’s dressing room with Guimaraes questioning the application of his teammates.

Bruno Guimaraes says how he really feels

“Like I said to the boys in the changing room, I think our strength is working hard and when we don’t work hard, things like this is going to happen,” the Brazilian told NUFCTV.

“We cannot think we are stars because we’ve got to a [Carabao Cup] final, we have to work hard every day. Like I said, our biggest strength is working hard but today we were very lazy. I think Manchester City played well but we were not good at all. We were so late in our pressing.

“We know how difficult it is to come here. I can accept a defeat but not in this way. Shambles.”

Guimaraes added: “We made it too easy for them. Like I said, we were very late in our press and they played through us. They have a lot of good players, we gave them the space and time, and they enjoyed it.

“I am not happy at all. Like I said, I accept the defeat but not the way we lost today. We have to work hard, no matter the reason or game. Everything was wrong.”

Champions League qualification still very much an aim

The defeat saw Newcastle slip to seventh in the league table, three points below the top four. However, Howe’s side can make up ground next week when they host third place Nottingham Forest at St James’ Park.

After losing their last two on home turf against AFC Bournemouth and Fulham, Guimaraes, who has set his sights on a return to the Champions League, knows the importance of a strong reaction.

“We need to be clear, everyone knows the performance today was not good at all,” said Guimaraes. “In our last four Premier League games, we’ve lost three - it is not good enough.

“The Premier League is very important for us, I want to get back in the Champions League but we cannot play like that and we cannot think about the final. We have to play well and gain confidence ahead of the final. Today, everything was wrong.

“I want to say sorry to the fans. They supported us and performing like that is so bad.

“We need to win the next game, especially at home. We’ve got two defeats in a row at home against Bournemouth and Fulham. We have to step up and get the three points because if we win the next game, we are going to be three points behind Nottingham Forest.

“It’s a big opportunity for us and we have to work hard this week to be ready.”
