With a couple of huge derbies headlining some key match-ups this weekend we've selected some of the best tifos we've seen from every club in the league's history.
There's no telling what Round 19 will throw up but with a #SydneyDerby, #F3Derby and #Archie200 all taking place hopefully there'll be one or two of these at stadiums around country.
Tweet us which banners we've missed and your favourite stadium shots from matches you've attended over the years! #ALeagueTifos
