The Football Association has charged Unai Emery after the Arsenal head coach kicked a water bottle that ended up hitting a home fan during the Gunners' 1-1 away draw to Brighton & Hove Albion on Boxing Day.
BBC Sport confirmed the FA's action, with English football's governing body feeling the incidentconstituted improper conduct. It was not detailed in the match officials' report of the game.
It means Emery could face either a fine or suspension ahead of a busy period of fixtures in both the Premier League and FA Cup. The 47-year-old can respond with an appeal or acceptance of the charge by Wednesday, January 2.
