Arsene Wenger faces further Football Association disciplinary action after describing disputed refereeing decisions as "concerning coincidences".
From beginning to end at the Emirates Stadium, both sides traded chances with Arsenal keeper Petr Cech and his opposite number Thibaut Courtois responsible for keeping the scoresheet blank until past the hour mark.
"The referees get away with you, with the English press, always no matter what they do", Wenger said.
The FA have released the following statement: "Arsenal manager Arsene Wenger has been charged following the West Bromwich Albion game on Sunday [31/12/17]". Bellerin re-tied the game two minutes into stoppage time with a spectacular half-volley of a partial clearance, yet Arsenal needed ex-Chelsea keeper Peter Cech to thwart Alvaro Morata one-v-one and escaped with a point when Zappacosta's follow-up shot struck the bar.
The North London club, which drew the first blood via a Jack Wilshere goal in the 63rd minute, had to settle for a 2-2 draw with the visitors. I knew before the game that the last 20 minutes could be hard for us, because we have a big disadvantage with the schedule.
A minute later Lacazette nearly doubled the lead but his shot inside the box was saved by Courtois.
And moments after Bellerin scored, the Spaniard was faced with another one-on-one but fired straight at Cech before Zappacosta followed up with a vicious strike that came off the bar.
"You see good football". He was harrying Chelsea's back five from the off and when he cleared out Cesc Fabregas from behind late in the first half, there was no shortage of passion in his vociferous protesting towards referee Anthony Taylor.
"I have been in football for 35 years, I know what I said after the game, I stand up for what I said", he said.
