Luke Shaw said it was unacceptable that Manchester United failed to beat Arsenal in the Premier League.
Ole Gunnar Solskjaer's side were held to a goalless draw at the Emirates on Saturday evening as they delivered a flat performance for the second game in succession.
The draw marked the second time in four days United have failed to win in the Premier League after they were beaten by Sheffield United in midweek.
It leaves United three points behind league leaders Manchester City - who have a game in hand - and defender Shaw said the draw with Arsenal represented a slip-up.
"[It's] two points dropped I feel," he admitted to Sky Sports. "I felt we were in control, Arsenal had a spell but we were comfortable and had countless massive chances we haven't taken. It would have been a brilliant result winning here, we have to be winning these games.
"The chances we had, I don't think it's acceptable to come away with a point - I haven't been in the changing room yet but I'm sure the lads will be disappointed.
"At times we were too slow. Second half we were sloppy and gave the ball away. We didn't look like we wanted to play. We created the chances and failed to score again and it cost us two points.
"We dropped points in midweek and again here. If we want to be in the title race we have to be winning these games. I don't know what more to say."
