Mikel Arteta says he will "have conversations" with his Arsenal players about their behaviour after picking up two FA charges in as many games.
Arsenal, who play at Tottenham on Sunday, have been charged with "failing to ensure their players conducted themselves in an orderly fashion" during Monday's FA Cup win at Oxford.
Arteta, 40, said the Gunners would do "anything we can do to improve".
He added: "We will always have conversations with our players and staff to see what we can do better [and if] we have to change any behaviour."
Tottenham manager Antonio Conte called on both sets of players to treat referee Craig Pawson with respect during Sunday's north London derby.
