Since the FFA Cup began in 2014, on eight occasions has a National Premier League club knocked off A-League opposition!
The first 'Cupset' was in the inaugural tournament, with Western Sydney Wanderers the first side to lose at the hands of an NPL team.
We had no Cupsets in 2015, but there were two in 2016, two in 2017, two in 2018 and one in 2019.
But can you remember which clubs have achieved the feat?
Take our quiz below. But be quick, you've only got 90 seconds to name all eight!
