It came just days after he was charged for a dressing-room rant at referee Mike Dean following Sunday's draw at West Brom, where Calum Chambers was harshly penalised for hand ball.
The Gunners boss has also been fined £40,000 for his behaviour, the FA has announced. We all knew that Arsene would get a bit of a break, to put it diplomatically, and the only wild card was how long that break would last, and how heavy the fine accompanying it turned out to be.
The Chelsea number 10 converted with aplomb, and although Arsenal ultimately rallied to a draw, the penalty had a telling impact on the outcome.
Describing the incident, Wenger claimed that the decision was a "farce".
He has until 18:00 on Tuesday, January 9 to respond to the FA's request.
When it was pointed out to Wenger that Jack Wilshere was accused of diving in the same match, he replied: "Maybe he did, but why should that change my opinion on the penalty? That is a concerning coincidence for me".
After the West Brom game, Wenger attacked the standard of refereeing in the Premier League, comparing it to the "dark ages", and was subsequently charged by the FA. Look since the start of the season; it is what we have to take.
"When you see how he shows his arm it is nothing to do with what happened". It looked like, mentally, we were shot and we could have lost the game but we had the resources to come back to 2-2.
