Argentina are throwing everything at the defence of their World Cup title – and they have needed to.
After being expected to steamroller past Cape Verde and Egypt in the first two knockout rounds, La Albiceleste had to fight tooth and nail for 3-2 victories.
But the win over Egypt came with an edge as the African nation asked Fifa to kick the officials in charge of their last-16 defeat out of the tournament.
Egypt have alleged bias in favour of Argentina and favouritism towards their star player, Lionel Messi.
After the game, coach Hossam Hassan said Egypt had been “treated unfairly” and “suffered injustice”.
Hassan went on to allege some kind of bias from Fifa.
“Perhaps they wanted to keep the world champion in the competition. Perhaps they wanted Messi to stay in the running,” he said.
BBC Sport examines whether there is anything in the conspiracy theory that everything is being set up for Argentina to succeed.
