We watched very exciting matches. Argentina literally played one-sided and scored only 2 goals due to Wojciech Szczesny's incredible performance. The score could have been very different if there had been someone else in the goal. Despite playing so badly, Poland advanced to next round. If Mexico had scored another goal, they would have come out, but they couldn't and they also conceded a goal in the final moments. I think Mexico deserved more to go to the next round. With such a performance, Poland gives no hope for the next round, they will probably be eliminated. Argentina, on the other hand, didn't allow any surprises, played well from the beginning and scored two beautiful goals despite Messi's missed penalty. Mac Allister had a good game as he played at Brighton and scored a nice goal. Julian Alvarez showed his quality, proving why he plays for the best club in the world. Messi can't always carry this team, other parts have to perform at a high level, if they really want to win the trophy.
I agree with what you said because if Szczesny didn't play well in this game of course Argentina could have scored more goals but luckily Szczesny played very well by making some crucial saves when there was an attack.
Even though he conceded 2 goals, Poland's position was unshakable in 2nd place which made them qualify for the next round with the goal productivity advantage of Mexico.
