Most pundits agreed, however, that while Hazard went down too easily, there was contact between his foot and Bellerin's, and that referee Anthony Taylor was right to point to the spot.
Wenger again criticised the scheduling that gave Chelsea an extra day's rest before this game, and said he knew before the game that Arsenal would get a refereeing decision against them.
With the game seemingly headed for a draw, Marcos Alonso put Chelsea ahead in the 84th minute, turning in Davide Zappacosta's cross after Mustafi failed to pick up his run.
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.
Nearly seven months later, Arsenal fans still had it in mind when Chelsea visited for a Premier League game on Wednesday. On the other end of the pitch, Alexandre Lacazette pirouetted through Chelsea's defense, but then waited half a second too long and bounced his shot off of Courtois.
But in the second minute of stoppage time, Bellerin produced an exceptional half-volley to earn the Gunners a point.
Chelsea had two quick chances to take the lead, first from Hazard whose low shot was saved by Cech's outstretched leg before diving full length to punch away Alonso's goal bound header. "I'm 35 years in football, I know what I say after the game and I stand up for what I said, no problem. Sometimes Wenger forgets that in the last few games [against Arsenal] we finished with 10 men". "At the end of the day, we always spend time on talking about things that are not really important in the game". In the 67th minute the ball bobbled up in the Arsenal box and both players went to contest the ball.
