Alexis Mac Allister:
Seriously, what a time to score your first international goal! Argentina had battered Poland during the first half. The xG was 1.98 to 0.23 in their favour. But they just could not find a way through. Hell, even Messi had messed up. Step forward Alexis Mac Allister, a man making just his 10th appearance for his country, to score the goal that was probably nearly celebrated as wildly in Brighton as Buenos Aires.
Wojciech Szczesny:
A second successive spot-kick save for the Poland goalkeeper, and what a beauty it was! Could Messi have better placed his penalty? Undoubtedly. But it was seriously well struck and it took an incredibly strong hand from Szczesny to parry it away to safety. Of course, while he may have won his personal duel with Messi, he still ended up on the losing side. Szczesny, though, was arguably the only Polish player who can be proud of his performance.
Julian Alvarez:
It wasn't so long ago that a starstruck Alvarez was getting photos with Messi. And yet here he was, playing on the game's grandest stage with his idol, and upstaging him too. It was a hell of a step up in class for Erling Haaland's understudy at Manchester City, but he proved himself an excellent young striker in his own right. There was plenty of pressure on Alvarez's shoulders after being asked to take over from Inter ace Lautaro Martinez up front, but the 22-year-old made light of it, sealing victory with a stunning strike into the top corner. A star has well and truly been born.
Argentina's fans:
It's only the host nation that's supposed to have home advantage at a tournament. However, Argentina's supporters ripped up the playbook here at Stadium 974. They turned this into a Qatari version of the Bombonera, and make no mistake about it, they played a pivotal role in this victory. They weren't even deflated by the penalty miss, with chants of 'Messi! Messi! Messi!' immediately ringing around the arena. With this kind of support at every ground they grace, anything is possible for Argentina in Qatar.
