No worries, will not happen. They have beaten no serious team yet, and even then they had plenty of trouble and could have lost these games.
Matching up with England now and then maybe France or Spain will definitely stop their run, I am super sure about that ( and obviously there is also a lot of hope this will happen since I dislike the ARG team a lot.

I have the same opinion, but even if I dislike Argentina I can not deny Messi is an alien level of football player and I can not say definitely that he will not carry the game or score a beautiful goal
I can not disrespect him and say they only won versus weak teams so they will lose now definitely. But I hope they lose

My own opinion and favoritism is that I want England to win because of Harry Kane and Bellingham. And England has not won a world cup in 60 years, I would be happy for them
