West Ham manager Avram Grant hit out at referee Michael Oliver after his side surrendered a two-goal lead in the 2-2 draw at Birmingham.
Grant felt that Oliver should have awarded his side a late penalty after City substitute Jean Beausejour appeared to pull back Lars Jacobsen inside the penalty box, and labelled the decision "a farce".
Grant said: "Harry Redknapp used the word farce about the decisions of a referee and I agree with him. The referee was five metres from the incident when the shirt of Lars was pulled and he did not give a penalty."
He added: "I'm very disappointed because this is not the first time it has happened to us.
"Similar things have happened against Wolves, Stoke, Aston Villa, Bolton and Manchester United where decisions have gone against us.
"What we saw from 50 metres, the referee could see from five metres and he needs to give a penalty. This is a farce.
"Sometimes you don't see things but this was in front of his eyes. I don't understand why he didn't give a penalty."
Grant took solace from his side's performance and said: "You saw a team that deserves to be in the middle of the table.
"We conceded a couple of easy goals and it cost us but if we continue to play like this, and show the same attitude, the points will come.
"We carried on like we have been playing in the last two games and Ben Foster made two unbelievable saves from Carlton Cole and Victor Obinna."
