Manchester United defender Harry Maguire has conceded their performance against Arsenal on Wednesday warranted their 2-0 defeat.
The Red Devils lost at the Emirates Stadium as a result of first-half goals from Nicolas Pepe and Sokratis Papastathopoulos.
Per Goal's Chris Burton, Maguire said:
"It was disappointing to go in 2-0 down at half-time because we should have weathered the storm, especially not conceding from a set play.
"When we're not playing great we've got to do the basics well and doing the basics is heading the ball out of your box and keeping the ball out of your net.
