Coach John van't Schip was pleased with the outcome and found plenty of positives in the triumph.

"There were some good things, some good goals, and of course, some things that need improvement, but overall I was satisfied with the performance and am very thankful that Oakleigh hosted us and played the match in a positive, attacking spirit," he told Heart's official website.

"It was a good opportunity for the boys to try out some of the things we've been working on, but we will analyse it again to see if they are on track for the upcoming season."

The coach introduced Matt Thompson (in his first game since ankle surgery), Gerald Sibon and Dean Heffernan into the starting XI for the first time.

"Those three guys didn't play last week, and we had some more players, like Marrone, who were also available. The mix between the young players and the experienced players worked well yesterday evening," he said.

"I was happy to see the work attitude of the team, although we have to work on a few things. But as a new team, that's normal, we have to improve and improve every time."

Sibon scored the first of his hat-trick after guiding home a Jason Hoffman strike, before the Cannons struck back through Ljuban Palinic.

Sibon curled a 35-yard free kick into the bottom right hand corner in the 55th minute, before securing his hat-trick four minutes later, tapping home after good work from Eli Babalj.

Babalj then earned his place on the scoresheet with the Heart's fourth of the night, dribbling past two players before slotting home.

Triallist Aziz Behich staked his claim for a permanent deal with Heart after blasting home to make it 5-1.

Oakleigh's Billy Gasparinatos rounded off the scoring.
