Arsenal manager Unai Emery has been charged by the Football Association for kicking a bottle which hit a Brighton fan towards the end of Wednesday’s 1-1 draw.
The FA said it amounts to improper conduct and Emery has until 18:00 GMT on 2 January to respond to the charge.
The Spaniard apologised for the incident, which was not included in the officials’ match report.
“I said to them I’m sorry,” Emery said after the game.
“It wasn’t hard but it touched one supporter.”
Emery went to speak to the home supporter immediately after the incident and again at full-time.
Speaking in his news conference on Thursday, Emery said he hoped the apology would be the end of the matter.
“I kicked the bottle in frustration but not at the supporters, not with this intention. It’s circumstances. I apologised. I hope it’s the end of the matter, yes,” he said.
