Saudi Arabia pulled off one of the great upsets in World Cup history this morning, beating widely-fancied Argentina 2-1 to bring the tournament to life and leave Lionel Messi facing the prospect of a humiliating exit at his final World Cup.
The two-time winners led through Messi, who is aiming to be world champion at the fifth attempt, but now face a battle to reach the knockouts after a remarkable second half from the Saudis.
