Chelsea remained third with 46 points, 16 behind leader Manchester City, which has 15 points more than second-placed United, while Arsenal stayed sixth.
After the draw with Chelsea, Wenger told Sky Sports: "When opinions always go the same way it's coincidence".
The FA have asked him to explain comments made both pre and post-match.
The Spain worldwide looked to have made a costly error when he clipped the foot of Chelsea's Eden Hazard in the penalty area which allowed the Belgian to make it 1-1 from the penalty spot after Jack Wilshere had put Arsenal ahead on 63 minutes. Bellerin's later equalizer wiped out Marcos Alonso's strike.
The Chelsea boss added: "I think it is a pity because when you have so many chances to score you must win the game".
FA question Arsenal boss Wenger about Chelsea comments
"It was a fantastic game and overall it could have gone both ways", Wenger said.
"You have watched the game which included favorable refereeing decisions for Tottenham?"
Wenger is contesting the FA charge.
"It was non-stop football, running up and down", said Bellerin. Nothing has changed. I've been in England for 21 years and I've tried to serve this game with honesty, integrity and when I have something to say, I say it.More news: Justin Timberlake channels Steve Jobs in 'Filthy' video tease
