"We've thrown it away in a way because we've had so much control of the match," the United boss said after the 1-1 draw.
"It's disappointing to lose two points for that.
"We had good chances in the first half and we played some fantastic football.
"It was a golden spell for us and these are the times you should be capitalising, but we didn't, and we've suffered.
"I think we're playing some great football. We were maybe a bit careless in the second half and we lived to regret that.
"You have to give credit to Everton for the way they fought back and I don't think you can deny they deserved a point"
