Encourage young footballers and ship them off early to Europe to play (preferably England so they're guaranteed English language skills). But many go into international skills in non english speaking countries and you can't tell the difference.
And then hope they play for Australia. There's no way we'll ever match them in investment so might as well leverage their resources to train our players.
Didn't count France as it was through a penalty shootout which could go 50/50. We beat them but it was far from convincing and even if we got to penalty shootouts for all our games it's unlikely we'd win all of them.
Yes we do have players but we don't have depth. England and Spain and even Sweden have 95 percent of players in the European leagues.
And in terms of Spain and England in top teams of top leagues. Someone playing for Sydney FC wouldn't even get a look in for the Spanish or English side.
