Argentina just beat France in what might've been the best World Cup final ever -- a nail-biter that came down to the wire ... and in the end, a good old-fashioned shootout.
The game had everyone at the edge of their seat through the full 90 minutes of regulation -- not to mention the extra 30 minutes that was played after things were left tied at 2-2. Lionel Messi scored Argentina's third goal in extra time, and then Kylian Mbappe responded by tying it up yet again ... sending the match into penalty kicks, where ARG eked it out.
