Brighton comfortably beat Man Utd 3-1 at Old Trafford on Saturday, condemning the hosts to their third defeat in five league games; they have not started a campaign as badly for 34 years.

Erik ten Hag says he had to take off Rasmus Hojlund because he cannot play a full 90 minutes

The Old Trafford crowd booed their players at full-time after a limp performance which followed an international break that saw Antony and Jadon Sancho taken out of the first-team picture.

Ten Hag felt Man Utd were unfortunate after VAR disallowed a first-half equaliser from Rasmus Hojlund after the ball went out in the build-up but admitted he was concerned about his side's results.

"We must stick together and stick to the plan and the rules and we will turn this around," Ten Hag said.

He added: "It bothers me [the form], but I have to see the way we play. It's about character, we have to see how strong we are and how the team sticks together. Players standing up and showing character because in all the games, especially the game today [Saturday] and against Arsenal and Forest, we have seen we can play well and create chances.

"But we also have some improvements to make and we have to step up."

Debutant Hojlund was taken off in the second half for Anthony Martial, who had scored two goals in his last 15 games, with Man Utd 2-0 down and chasing the game.

The Old Trafford crowd openly booed the decision before applauding Hojlund's promising first home performance following his £72m move from Serie A side Atalanta.

Ten Hag says he was being cautious with Hojlund, who arrived at the club with a stress fracture in his back, but insisted there was no ill feeling towards Martial.

"I think it was positive," he said. "You see from the fans in first moment at Old Trafford, the reception was great. Hojlund performed very well, good that they gave this signal, this message will give Rasmus belief. He came in with small issue, he's not ready for a whole game.
