Brisbane Roar
I can't actually find anywhere to confirm if this change from orange/black to orange/maroon is a permanent change, or simply a variation they're using this season as part of their 20th anniversary.
I'm not the biggest fan of how the orange and maroon look side-by-side, but it does tie the team back to Queensland a little more which is something fans have wanted since the new crest was first introdcued a decade ago.
