Moore Park was chock-a-block full of budding young athletes and aspiring footballers at this year's Open Athlete Assessment Trials last week.

Kids by the hundreds flocked to Lakeside Oval, across the Under 10, 11 and 12 age groups, for the annual three-day program run by experienced academy coaches.

The groups even had some special guests drop by including Sydney Swans skipper Josh Kennedy, speedster Gary Rohan and ruckman Sam Naismith.

Check out the best snaps from the trials below.
