Arsenal manager Arsene Wenger was not impressed with referee Robert Madley in the wake of his side's 3-1 Premier League defeat at the hands of Liverpool on Saturday.
First-half goals from Roberto Firmino and Sadio Mane saw Liverpool surge ahead before Danny Welbeck pulled one back after the break.
Georginio Wijnaldum eventually made sure Liverpool emerged victorious with his goal well into stoppage time, but Wenger has suggested things could have gone differently had Emre Can been sent off in the second half after a strong challenge in midfield just minutes after receiving a yellow card for a foul on Alexis Sanchez.
"I felt we were a bit unlucky and a bit unlucky with some decisions as well," Wenger said at a media conference.
"You watch the situation and you give me your opinion whether Emre Can should have been sent off. Or you ask the referee, that's even better. You go directly to see him.
"No, I did not go to see the referee after the final whistle. I do not need explanations. The situations are the situations. Explanations will not change anything in the situation."
Wenger was heavily criticised for his decision to leave Sanchez out of his starting XI, with the Chilean impressing after coming on at half-time, but the Arsenal boss was adamant he did not have any regrets.
"I just think that I have no special regrets," he added.
"My regret is to have lost the game and especially in the first half, for the first goal we conceded from a direct kick from their goalkeeper."
