West Ham United boss David Moyes was left angry by Liverpool's equaliser for Saturday's 2-1 defeat.
At 1-0 down, Mohamed Salah earned and converted a penalty after being fouled by Arthur Masuaku.
Moyes said, "I'm amazed that a penalty was given in the first half. I can't believe that we're allowing those sorts of penalties to be awarded.
"We weren't clinical enough at times. We missed a couple of really good opportunities to get another goal.
"In a lot of games we feel we can challenge. We go into many games thinking we've got a chance. I wouldn't say we were unlucky today, but I'm really disappointed when we were 1-0 up that the penalty was given."
The Scot continued: "It's not the sort of football I want to be involved in. I think our player stops and throws his arms up because he's so disappointed about the dive.
"I'm just disappointed they didn't turn the decision around. Maybe in the second half the decision [Jota's disallowed goal] went for us, but the first-half one didn't."
