Liverpool manager Kenny Dalglish was angered by referee Michael Oliver's decision-making in their 1-1 draw at home to Aston Villa.
Chris Herd put the visitors ahead in the 10th minute and it took until the 82nd for the Reds to equalise, with Dalglish unhappy with two penalty appeals which were turned down by Oliver.
In the second half, the ball hit Eric Lichaj's hand as Dirk Kuyt tried to go past him. Oliver apparently then told Kuyt that Lichaj had been unlucky, and Dalglish said: "I have never heard of a penalty not being given by a referee who said the boy was unlucky - what chance have we got?"
He continued: "I can only tell you what they were saying in the dressing room - don't ask me to justify it. When you consider the penalty was refused because the opponent was unlucky, it just doesn't add up."
Dalglish also claimed a challenge in the box on Luis Suarez by Alan Hutton should have been a penalty, while he said the ref also got it wrong by later booking the Uruguayan for diving.
"Even Suarez's booking, the guy has trodden on him and it is a joke," he said. "You can imagine the headlines - he got booked for diving and the guy (Stephen Ireland) has actually trodden on him and he is lucky he has not broken his foot.
"And Hutton was a bit fortunate in the first half."
But Villa boss Alex McLeish disagreed with Dalglish over the penalty incidents.
"I've not seen them. I know the one in the first half they claimed for, my IT guy gave me a report that it wasn't a penalty," he said.
"It is difficult to know what is deliberate [handball] and what is not, it is a grey area."
