Three A-League fans have been charged after bad behaviour before, during and after a Sydney derby at Parramatta Stadium last night, police say.

Several flares and smoke bombs were lit before and during the match between Sydney FC and the Western Sydney Wanderers, with one leaving a 16-year-old girl with a minor burn to her foot.

Sydney FC won the match 2-1 after a 90th minute goal in front of a record 19,627 crowd at Parramatta Stadium.

A 34-year-old man was issued with a field court attendance notice and a 12-month venue ban for allegedly lighting a flare inside the stadium.

A 26-year-old man was arrested and charged after he was identified as a banned supporter, serving a Football Federation Australia ban until 2023.

He was charged with entering enclosed lands and granted conditional bail to face Parramatta Local Court on Wednesday.

A man, 24, was charged with common assault and issued with a field court attendance notice after allegedly getting into a fight with other fans while leaving the stadium.

Two other fans were issued with infringement notices for allegedly entering the playing field and for offensive behaviour.

In a statement, police said most fans enjoyed the night without any problems.

"The vast majority of fans who attended the match last night enjoyed it in the right spirit," Parramatta Local Area Commander Superintendent Wayne Cox said.

"At any public event, the number-one priority for police is community safety."

Western Sydney Wanderers fans were in the spotlight for bad behaviour in October after premeditated brawls broke out, flares were ignited and missiles thrown during a match at Sydney Football Stadium.

Head coach Tony Popovic said at the time, the unruly behaviour and violence by fans was unacceptable.
