Saudi Arabia stun flat Argentina to ignite World Cup

Saudi Arabia notched one of the biggest shocks in World Cup history with a 2-1 win over Lionel Messi's Argentina thanks to a scintillating second half comeback.

On his fifth and final quest for the only major trophy to elude him, the 35-year-old Messi scored a 10th minute penalty in a dominant first half display where he and Lautaro Martinez also had three goals disallowed for offside.

But Saudi Arabia, the second-lowest ranked team in the tournament after Ghana, threw caution to the wind at the start of the second half, charging at Argentina's defence in front of a frenzied crowd.

Saleh Al-Shehri squeezed in a low shot in the 48th minute while Salem Al-Dawsari curled in a scorching strike from the edge of the penalty area in the 53rd minute to leave Argentina and Messi looking utterly shell-shocked in the Group C opener.

Despite plenty of possession after that, Argentina were unable to penetrate Saudi Arabia, who were competing in their sixth World Cup but had never previously won an opening game.

Both teams have Mexico and Poland to come, with Argentina needing an immediate reaction if Messi is to have a realistic chance of matching Diego Maradona's immortality in his homeland by bringing home the World Cup.

The result broke Argentina's 36-match undefeated run and stopped them from matching the previous international record of 37 games unbeaten held by Italy
