You ask me if it's a penalty, I say it's a farcical decision.
Chelsea had 19 of the 33 chances on goal in the match, with top-scorer Alvaro Morata wasting three one-on-one opportunities.
"The referees get away with you, with the English press, always no matter what they do", Wenger said.
Back came Arsenal in a thrilling finale as Bellerin's whipped effort flashed past Courtois in stoppage-time, but the Gunners nearly lost it again as Cech thwarted Morata before Zappacosta thundered the rebound against the crossbar in the dying seconds.
A share of the points mean that Chelsea remain third, one mark behind Man Utd, while Arsenal are sixth - five points shy of the top four.
In the end, a point each was probably a fair result in what must go down as one of the most entertaining games of the season. The last shot should have been a goal.
However, Alonso produced a clinical finish from Davide Zappacosta's low cross on the right to slot past Cech from six yards out, although there was more drama to follow when Bellerin steered a half-volley into the left corner of the net from 18 yards out.
Hazard dispatched his spot-kick to equalise before Marcos Alonso appeared to have scored a late victor for the visitors when the Spanish left-back got on the end of Davide Zappacosta's cross.
"I've been in England for 21 years and I try to serve this game with honesty and integrity and when I have something to say I will say it. What I've seen and heard in the corridors from people, you might understand that I'm surprised and shocked at having been charged". "When we looked as though maybe mentally we were shot, we had the resources to come back to 2-2".
