Robben was on the end of stinging criticism from Wenger who said Robben "made the most" of his tussle with Wojciech Szczesny.
The Gunners stopper made contact with Robben and the referee had no choice but to give a penalty and dismiss the Pole.
Robben said: "Wenger's comments are typical for a losing coach.
"I don't care much about it, because it's not the first time he acts like this.
"It was a pretty scary moment for me. I picked up a serious injury in December after a similar foul from Augsburg's goalkeeper."
