Blink and you'll miss it – the first Los Angeles derby of the LAFC era has come and gone.

While Los Angeles Football Club will not see their first team take the field until the 2018 MLS season, their academy's Under-12 side (pictured above) make their US Soccer Development Academy (USSDA) debut when the 2016-17 season opened this weekend, and the games came against none other than their city rivals, the LA Galaxy:

The first game ended in a 3-3 tie, but the second produced a winner – and it was LAFC who struck the first blow:

And – it being the first L.A. derby, so to speak – the fans were out in force to cheer their boys to victory:

No doubt they went home happy. And it's likely the LAFC front office did, too, having seen the first tangible result after a making a big push to get their academy started and establish a presence in the L.A. youth soccer scene.
