West Ham manager Manuel Pellegrini speaking to MOTD: "In football, you must score. We dominated the game and tried to create options to score.
"We had two or three chances and must decide the game by scoring. We didn't and lost two points.
"I am happy with the attitude of the team. It's not easy to create chances against Sheffield United but we did. In the second half we didn't do it as much.
"But the points dropped at home - today and in our last match against Crystal Palace - can make the difference in our season.
"Today we had the feeling we can do it better because we dominated part of the game and had chances to win it."
