This follows a similar operation earlier in the season when Bonnyrigg entertained United in the NSW Premier League.

Only Sydney United accredited members and box holders, around 250 people in total, will be admitted to the game next Sunday following discussions between the two clubs, Football New South Wales and the Police.

A statement on Football New South Wales' official website today said: "Strict security measures have been put in place to ensure the safety of all players, officials, members and local residents."

United have a strong Croatian support while Bonnyrigg counts on a large Serbian following. The fixture has proved a flashpoint in the past with violent clashes.

Parents, partners and relatives of players and of match officials will not be able to gain entry to the match.

"This will protect the match from any outside influences not connected with the sporting contest between these two iconic clubs," continued the statement.

"All media groups have also been restricted access to the game."
