Unai Emery has been fined £8,000 after being charged with improper conduct by the FA.
The Arsenal boss kicked a water bottle into the crowd which hit a Brighton fan during the Gunners’ draw at the Amex.
The FA announced on Thursday afternoon that the 47-year-old had been charged over the incident.
“Arsenal manager Unai Emery has been charged following the game against Brighton yesterday [26 December 2018],” a statement read.
“It is alleged his action of kicking a water bottle during the fixture amounts to improper conduct. He has until 6pm on 2 January 2019 to respond to the charge.”
Emery apologised for the incident to the supporter in question immediately after full-time, and had hoped that would be the end of the matter.
But he has been sanctioned by the FA to the tune of £8,000.
Speaking ahead of his side’s defeat to Liverpool, Emery said: “I say yesterday my apologies, I kicked the bottle in frustration but not for the supporter, I kicked for me and it went near to the supporter and I said to them my apologies. There is not another communication.
“I repeat today my apologies for my individual action but I kick the bottle because it is near me, but not because it is my intention..
“I have to respect the decision because it is a circumstance of my action but not another intention from me with the supporter. I say to them my apology.”
