Football Federation Australia boss James Johnson wants the local game to wade into the global debate over FIFA's revamped Club World Cup, which has the potential to provide a multi-million dollar injection into the A-League.

The brainchild of FIFA president Gianni Infantino, the new-look Club World Cup is set to launch next year in China and could feature an Australian team if Sydney FC, Perth Glory or Melbourne Victory manages to make a deep run in this season's AFC Champions League.

That would trigger an eye-watering cash bonanza for the A-League, with The New York Times reporting this week that FIFA has engaged an American financial advisory firm, The Raine Group, to source the US$1 billion ($1.53 billion) it needs to get the 24-team concept off the ground.

Johnson has intimate knowledge of the Club World Cup proposal - he was involved with its development during his time as FIFA's head of professional football, and as secretary of FIFA's football stakeholders committee, has first-hand knowledge of how it has divided the world game.
