United boss Ole Solskjaer expressed his frustration with the nature of his side's concessions as they shared one point with Everton after a draw in the English Premier League clash on Saturday.
"We conceded three goals from three shots on target," Solskjaer lamented.
Solskjaer also expressed his unhappiness with the amount of time added on, with Everton scoring in the fifth minute of injury time after four were signalled.
"Why was there were four minutes? That's beyond me," said Solskjaer. "All we had to do was get the ball in the corner and see it out. But we didn't.
"We didn't deserve to be 2-0 up at the half time - we scored fantastic goals but we dilly-dallied too much. We had possession but it was too slow.
After they scored we played some very good stuff. We should have seen it off by scoring the fourth. I think the front four played well and caused them problems but that wasn't the problem.
"Results create the mood, and the last kick of the ball makes us go home really disappointed as we've lost two points on a long thump through the middle, which we should have defended better. But if you look at the overall performance the second half was good."
United sit second with 45 points, 2 behind league leaders and local rival Manchester City, while Everton are 6th with 37 points and 2 games in hand.
In a match where the host dominated, they left frustrated as Everton dented United's league title race but also gave themselves a boost for at least a European football.
