35-year-old Messi, playing in his fifth and probably his final World Cup, gave his team a phenomenal start by putting ball inside the net inside first 10 minutes but later in the second-half, stunning goals by Saleh Alshehri and Salem Aldawsari within just five-minutes gave Saudis a historic win. Saudi Arabia's previous biggest win was 1-0 over Belgium at the 1994 World Cup.

Reacting to Argentina's shock defeat, Messi said his team isn't going to give up after 'heavy blow' and will try to get a win over Mexico in their next Group C match.

"It's a very heavy blow, a defeat that hurts, but we must continue to have confidence in ourselves," Messi said after Argentina's 2-1 loss. "This group is not going to give up. We will try to beat Mexico," he added.

Speaking via Argentina’s official Twitter account, Messi said: “We knew that Arabia is a team with good players, that moves the ball well and that advances the line a lot. We work on it, but we speed up a bit.

“There are no excuses. We are going to be more united than ever. This group is strong and they have shown it. It is a situation that we did not have to go through in a long time.

“Now we have to show that this is a real group. It’s a very hard blow for everyone, we didn’t expect to start like this.

“Things happen for a reason. We have to prepare for what’s coming, we have to win or win and it depends on us”.
