Jose Mourinho’s side defeated their London rivals 2-0 at Stamford Bridge, with the Gunners reduced to nine men after dismissals for Gabriel Paulista and Santi Cazorla.
Wenger, who has a long-standing rivalry with Mourinho, expressed his anger during the match as the universally-loathed Diego Costa took every opportunity to rile and abuse his players.
Indeed, Gabriel’s sending off was due, in no small part, to the antagonism he had received at the hands of Costa, who goaded the centre-back regularly. Gabriel eventually cracked, and was dismissed for kicking out at the Spain forward.
Speaking to reporters after the match, Wenger insisted that the controversial striker receives some kind of punishment for his actions.
“Yes, of course [the FA should take action]. They do it for everybody,” Wenger began, as per Goal.
“Especially I would like [referee] Mike Dean to look at the whole action that happened during the game and see if he stands for his decision.
“They [the match officials] can tell you and they know Diego Costa. He is not a newcomer. He was here for a year now.”
The defeat leaves the Gunners in fifth place in the league, having won three, drawn one and lost two of their matches to date. On 10 points, Arsenal find themselves five points behind leaders Manchester City.
Despite defeating their rivals, Chelsea remain in 15th place, three points behind Arsenal.
