Lionel Messi. It just had to be, didn't it?
Just when his country needed him the most, he popped up with a moment of magic to keep Argentina's World Cup dream alive and sink Mexico at the Lusail Stadium on Saturday night.
What had been a dismal affair was lit up by Messi on 64 minutes when he drilled a perfect shot into the bottom corner from 25 yards to break the deadlock.
And he then set up Enzo Fernandez for a stunning second late on to seal a crucial victory for Lionel Scaloni's side.
It was a win that revitalised Argentina's hopes in Qatar following their shock 2-1 defeat by Saudi Arabia in their opening group stage game.
And while they were far from their best once again, they now know that victory over Poland on Wednesday will seal their spot in the last 16.
