Youth and speed paid off well for Brisbane, and they only had a couple of 'big names' or old heads in their squad.
What tends to happen in the A-League is that teams watch what wins a Premiership then try to emulate it. Style of play that is successful has been different for just about every A League season.
Best thing for us to do is develop our own style of play that will combat what everyone else will try and do next season (ie don't fall for the trap of thinking Youth + Speed = Champions next season)
