Mexico is out of the World Cup on goal difference!
Mexico beat Saudi Arabia but the third goal wouldn't come. Argentina beat Poland but the third goal, which would've gotten it done for El Tri, wouldn't come. When the final whistle sounded at Lusail Stadium, bringing the insanity of World Cup Group C to a close, it confirmed Argentina as winners and Poland as runners-up on goal difference (Poland's zero vs. Mexico's negative one).
It had been even closer than that.
