Arnold cited under Code of Conduct
The action relates to comments made in the official post-match press conference following the Sky Blue's 2-1 loss to Adelaide United on Friday.
Arnold branded the conclusion of the game "criminal" after the ref's decision to award the Reds a stoppage time penalty.
“If I could start by saying, that I don’t really want to be sitting here tonight,’’ Arnold said after his 10-man Sydney came away with nothing.
“So I just want to make a statement and then I will leave. Congratulations to Adelaide for winning the game. I’m very proud of my boys they worked extremely hard, 11 against 10, I thought we did exceptionally well and it was criminal how it ended.
“That’s pretty much all I’ve got to say. I’d rather you guys write what you saw. It’s better than I don’t saying anything because last year I copped a $5000 (fine), you’re not allowed to have an opinion in this game.
“Dylan McGowan said it wasn’t a penalty. He said it to the players.”
Arnold has an opportunity to provide a submission by 5pm on Monday, December 21.
The sanctions applicable for a breach of the FFA National Code of Conduct include a reprimand, a fine and/or suspension from participation in a match or match.
