Argentina do have a history of poor sportsmanship on quite a few occasions, I think it doesn’t really belong in the beautiful game. A world cup should be a celebration of sport, not a to-the-nails battle for winning.
For me, Brazil are the team that should have won this World Cup. They had so much talent that at times they took it a little too easy. Croatia, however much I like them for being the plucky little outsiders, didn’t really have the forwards to make it an even game, against Brazil or Argentina.
But you can’t really deny Messi the chance to make it “his” World Cup, he has been brilliant for such a long time, and he has the talent to unlock even the best defenses, if given room. I would like to see a Argentina v France world cup final, it would be a more even contest.
