Everyone loves a good theory, particularly when it comes to sport. Well, with that in mind, Chelsea supporters have come up with a brilliant one for this year's World Cup.
Four teams remain in the competition. Croatia take on Argentina on Tuesday in the first of the two semi-finals as Luka Modric and Lionel Messi embrace their last realistic chance of winning their respective countries the biggest prize in football.
Then on Wednesday, this year's surprise package Morocco play the current holders France in what promises to be another exciting affair. If the north African's were to win the competition, it would be one of - if not the - greatest underdog story in the history of the sport.
