It makes no sense why people are so confident in teams that really aren't that good, for example Italy. Look at tonight's game. They drew with Paraguay. There was no reason for it, it's not like Italy had all of their good players injured or that Paraguay were particularly good, it's just that Italy aren't as good as people think.
It cheeses me off when people say 'Forza Azzuri' or 'Viva Italia'. Are you Italian? No. So Stop it.
