With the Gunners in cup action for their next two fixtures, the disruption to their league schedule will be minimal even with a three game ban.
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.
No wonder Wenger was in full deflection mode after dropping yet more points in a 2-2 draw with Chelsea on Wednesday.
In response, Hazard joked: "We don't need a replay, yes it's a penalty".
Arsenal boss Arsene Wenger handed three-match ban over referee comments
"I don't know... maybe I would've gone home and commit (sic) suicide tonight", Wenger jokingly told journalists at the post-match press briefing.
Wenger was vexed by north London rival Tottenham winning 2-0 at Swansea the previous night to go a point ahead of Arsenal with a game in hand.
The Arsenal manager will be banned from the touchline for Sunday's FA Cup tie at Nottingham Forest, the first leg of the League Cup semifinal against Chelsea next week, and a Premier League match with Bournemouth on January 14.
The result will likely cause more frustration for Arsene Wenger, who was hit with an FA charge after complaining about the penalty awarded to West Brom in last Sunday's 1-1 draw at The Hawthorns, though, as it means his side stay sixth in the table, five points adrift of the top four. 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.
