Man United have drawn to Burnley, Stoke City, Arsenal and West Ham, Herrera was undoubtedly disappointed that the squad could not make their dominance count with a goal lead.
“Another game the same,” he said. “We control the game completely from the kickoff. They score a very lucky goal and then we control and create chances.
“Their keeper was the best one more time. That happened against Stoke, Burnley and Arsenal. We don’t know what we have to do to win a game.
“We have more possession than the opponents. I don’t know, honestly.
“I have had a run like this but not playing good. The way we are playing we are controlling the whole game from the kickoff.
“Football is about scoring goals and finishing and we are not doing that right. It is true.”
Man United deserved to walk away from Old Trafford with all three points but failed to remain clinical in front of goal.
With another fixture against West Ham on Wednesday in the League Cup, United will be hoping for a better result.
