LUSAIL, Qatar -- Saudi Arabia pulled off one of the biggest World Cup shocks ever to come from behind to beat Argentina on Tuesday.

Argentina, one of the favourites to lift the trophy, dominated the first half and went ahead through Lionel Messi's first-half penalty. But a stunning fight back from Saudi Arabia after the break saw Saleh Al-Shehri and Salem Al-Dawsari both score in the space of five minutes to leave Argentina defeated for the first time since June 2019 -- a run of 36 incredible matches.

Rapid reaction

1. Saudi Arabia cause one of the biggest shocks ever

Argentina don't start World Cups well, but this was a stunning upset even for them. Saudi Arabia, ranked 51st in the world (between Qatar and Greece), scored twice in five chaotic minutes early in the second half to record one of the competition's biggest ever shocks -- similar to Cameroon beating Diego Maradona's reigning champions in 1990.

Saudi Arabia were barely in the game during a first 45 minutes dominated by Argentina and headed off the field at half-time looking like a team clinging on for dear life. But goals from Saleh Al-Shehri and Salem Al-Dawsari -- a right-foot effort that flew into the top corner and an early contender of goal of the tournament -- capped a remarkable turnaround.

And when the impetus was on Argentina and captain Lionel Messi to find a comeback, they lacked composure and precision in front of goal.

Argentina will cling to the fact that after losing to Cameroon in their opening game of the 1990 World Cup they still managed to reach the final. But after arriving in Qatar as reigning South American champions and on the back of a 36-match unbeaten run, this campaign was meant to be different. Just as they did at Russia 2018, it looks like they are again going to make hard work of the group stage.

2. Argentina only have themselves to blame

Lionel Scaloni's side should have been out of sight at half-time but somehow found themselves behind early in the second half. They only had themselves to blame; with a bit more care, they could have been 5-0 up at the break.

Messi had a good chance saved by Mohammed Al-Owais. After the penalty they had three goals chalked off because of offside, twice from Lautaro Martinez and another from Messi.

Saudi Arabia came into the World Cup with a reputation of finding goals hard to come by. Despite failing to register a single shot in the first half, they managed to beat Emi Martinez twice in five minutes in the second half.

What will worry Scaloni most is that Argentina had more than 30 minutes after going behind to force a draw or even win the game, but they quickly resorted to pumping crosses into the box which the Saudi defence mopped up with ease. With games against Poland and Mexico to come, Argentina will still believe they can qualify for the knockout rounds but it was not the start they were expecting.

3. Saudi Arabia back up fans' confidence

Saudi Arabia supporters have crossed the border into Qatar in their thousands and arrived genuinely hopeful of matching their performance at the 1994 World Cup in the United States when they reached the round of 16.

Perhaps before the tournament kicked off, they were the only ones who believed it but not anymore. Most of the supporters who travelled to the Lusail Stadium early on Tuesday morning admitted they were not expecting much from the game vs. Argentina and thought they would likely have to pick up points against Poland and Mexico to progress from Group C. Instead, they dealt a huge win for football in Asia -- especially after both Qatar and Iran opened their campaigns with abject performances against Ecuador and England, respectively.

It was only after half-time that they began to defend like a team that kept six clean sheets in qualifying. Their last World Cup began with a 5-0 thumping by hosts Russia, but what a difference four years can make: a day that will go down in both the history of Saudi Arabian football and the World Cup itself.
