Speaking ahead of his side's Champions League home clash against Sevilla, the Spaniard said he would do the same again.
"The game was conditioned by the decisions that were made and it was my duty to be defending my players, supporting my players, supporting my club, defending my people in the best possible way.
Arsenal issued a statement on Monday defending Arteta and said the club "deserved better", adding that the officiating body, the PGMOL, urgently needed to address the standard of officiating.
"The moment you have a chance in football to put it to bed, do it," Arteta said.
"We will have to do a lot of things right tomorrow against a really good team with enormous experience."
