"It is an advantage, but I can't say it is a great advantage with 16 games left," the United boss said after the game.
"We have a difficult game away against West Ham next week and there are a lot of difficult games in the run-in and teams will drop points.
"I think we had a lot of chances in the match but we never put Everton to bed. A second goal would have put the result in our favour without question.
"If you are not taking that second chance you are not sure of the game and Everton kept going because of that, showed great resilience and athleticism and took it right to the wire.
"It is always better to be top of the league than anywhere else.
"We just hope we don't drop as many as the rest. I'll be looking for a draw on Sunday."
