Arsene Wenger complained his side were denied a goal and a penalty by incorrect decisions during their 1-0 loss at Stoke on Saturday.
A 72nd-minute strike by Alexandre Lacazette effort ruled out for offside should have stood "100 per cent", according to Wenger, who also suggested that the Gunners should have been awarded a penalty in the first half when Hector Bellerin went down under a challenge from Mame Diouf.
"I believe it is the kind of night where you are angry,” said Wenger.
"That is because not only did we not score with the number of chances we had, we made stupid mistakes centrally for the goal, first by losing the ball and after by not defending properly.
"And on top of that as well I think we were unlucky with some decisions from the referee because we scored a regular goal."
Replays showed Lacazette's boot may have been offside when the ball was played to him before he fired in.
Wenger was adamant the goal should have stood: "One hundred per cent. I just watched it and it is not offside at all. Even his foot was not offside."
Then, when asked about the Bellerin-Diouf incident, he replied: "Yes, of course, but we know we don't get penalties.
"Look at the numbers and you will see. We had last year the highest (number of) penalties against us at home by a mile and the lowest number for us. So I give you just the numbers. I don't say anything else."
