Wenger is already facing an FA charge for his criticism of Mike Dean after Sunday's 1-1 draw at West Brom, and was seething once again after Anthony Taylor awarded Chelsea a second-half penalty for Hector Bellerin's challenge on Eden Hazard in the area.
It was a game that had everything in it - two goalkeepers in excellent form, Jack Wilshere scoring a cracking goal when he arguably shouldn't have still been on the pitch, numerous mistakes in both teams' defences that went unpunished and a controversial penalty call.
"At some stage in football you have to stand up to the referee's decisions".

Of course, this being Arsenal, Chelsea still managed to fashion another chance to steal the victory, only for Zappacosta's powerful effort to come back off the crossbar after Morata has missed another great opportunity.
ARSENE WENGER, Arsenal manager, blaming his team's second consecutive league draw on referee's decision going against them.
It was tough for the Gunners to take, given their part in a rip-roaring contest in which Thibaut Courtois had made a series of brilliant saves to deny Sanchez, Mesut Ozil and Alexandre Lacazette. D efender Bellerin later netted an equaliser in stoppage time. Castigating press for not talking about football, and not criticising refs, having himself willingly talked about refs, and then talking about how we have to accept refs have impossible job. Er...
"We looked like we were mentally shot and could have lost the game - we had the resources to come back to 2-2". "I think he is at the level now where not many people expected him to be", Arsenal manager Arsene Wenger was quoted as saying during a news conference.
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.
