West Ham boss David Moyes branded their 2-2 draw at Sheffield United the worst performance of their season.
Oli McBurnie, from the spot, scored the latest ever goal in the Premier League, converting a 103rd-minute penalty to earn a point for the Blades. Rhian Brewster for United and West Ham's Vladimir Coufal saw red in injury-time.
Moyes said, "We should never have got ourselves red carded, we got caught on the ball in midfield.
"Really, we had the chances to win, we had great chances to make it 3-0.
"We went down to 10 v 10 in the last minute but even so that wasn't a problem, we should have defended it.
"We defend as well as we could have done and a couple of decisions didn't go our way.
"It was not good, probably our worst performance of the season as far as quality on the ball and quality of decisions.
"I wouldn't like to blame the pitch but the pitch was quite hard, but I'd only be making excuses if I'd done that. That may be a reason for some of the poor passing in the first half."
He also said: "Disappointed in the end because we should have comfortably got ourselves three points today. I see it as two points dropped.
"Look, I'm not going to come out and say much because we're the ones who would get in trouble. We'd like to, but we're getting to a stage now where the managers we're seeing a level of officiating where we're shrugging our shoulders and saying, 'this is what we're getting now'.
"We should have done better, we had 11 v 10 and we got caught in midfield to go down to 10. We were a little bit late in the challenge which I don't think was enough for a booking but it warranted one, the referee thought so and that's all we can do.
"So, 10 v 10 should still be fine, we shouldn't concede at that point. I'm not sure the decision was correct, but over people will have other thoughts on it.
"We were so poor, probably as bad as we have been with the ball. It was another call which did go against us which on another day could have gone for us and we could have come away as winners and we'd be talking a lot more positively.
"Our standards are not where we want them to be."
