Cahill was audibly booed by Sydney FC supporters when he came on as a substitute during a 1-1 draw at ANZ Stadium on Friday night.

The Socceroos legend took to Twitter to address the heckling, warning supporters to be wary of their conduct around young fans.

"Is what it is, i don't mind the boos but remember what comes out of FANS mouths stays with the children as much as it does me," Cahill tweeted.
