The Danish striker, who came on in the second half of the 3-1 defeat to Sir Alex Ferguson's side, was photographed exiting a nightclub, looking a little worse for wear, in the early hours of Wednesday morning with his trousers pulled down.
The 21-year-old was fined a week's wages for his inappropriate behaviour, with Wenger labelling his conduct as 'unacceptable'.
However, the Frenchman has since revealed that Bendtner insists he was not drunk, and that his trousers had been pulled down as a prank.
“I was angry when I saw the pictures but he has been set up," he said in The Sun.
"He was not drunk but somebody was waiting for him to leave the club and pulled his pants down from behind.
"Then they took a picture and posted it around the world. That’s what he told me.”
