Perth Glory secured the A-League Premiers Plate for the first time on Sunday as Ivan Franjic's goal sealed a 1-0 win over Newcastle Jets.
Sydney FC had opened the door for Glory to clinch the A-League premiership after drawing with rivals Western Sydney Wanderers on Saturday, and Tony Popovic's side did not disappoint.
They started brightly and struck the post through Andy Keogh, while Diego Castro and Joel Chianese both had goals ruled out for offside.
They finally broke the deadlock in the 65th minute when Franjic latched onto Castro's ball into the box and fired past Jets goalkeeper Glen Moss.
