West Ham manager Avram Grant felt his side had done enough to secure a first league win since the end of September after the goalless draw against Blackpool.
They had two strong penalty claims turned down by referee Kevin Friend in the first half when winger Pablo Barrera was tripped by Stephen Crainey and then Victor Obinna's shot hit Craig Cathcart on the arm.
Grant again faced calls for his resignation after the final whistle but said: "The supporters saw the effort everyone has given. Some were disappointed from the game of course, because the result is not good.
"There were enough chances to win three games and enough penalties to win two games. We did everything right. I cant say a bad word abut the players, they pressed well, moved, passed and created a lot of chances."
