Sorry for coming in this late, but let me put in some words.
About Senegal vs. France. Greatest upset ever? Puh-leeze!
Just a few that would easily rank over it:
1 - Brasil (at home) losing to Uruguay in 1950 final;
2 - Hungary losing to Germany in 1954 final;
3 - Netherlands losing to Germany in 1974 final;
4 - Netherlands losing to Argentina in 1978 final (Neeskens could have won the game in the last minute of regulation. Instead, hit the post and his team lost in overtime);
5 - Brasil losing to Italy in 1982;
6 - Brasil losing to France in 1986 (though this is as close an upset as it gets. France was a very good team too);
7 - Argentina losing to Camerron in 1990;
8 - Netherlands losing to Brasil in 1998.
And these are just the ones that come to my mind in a flash. Any research would bring other upsets of a greater magnitude than Senegal vs. France to mind.
About favorites. Argentina and Italy.
But especially Argentina. They are SO much better than everyone else that it would be a shame to see them lose (and I am a Brazilian. We don't especially like the Argentinians over here...long-time rivalry and all that).
But Italy has a team that plays a very effective, though bureaucratic, football.
I don't think Brasil has a chance, and I won't even cheer for my country.
I particularly hate the coach, who has imposed an european style of football on our team, has left Romário (still the best player in the world, regardless of FIFA elections - remember, in the past they chose Ronaldo twice, when Roberto Carlos was playing WAY better than him the second time around) here, for personal disagreements with him, and has called some very questionable players to the team, just because they play for european teams and make a tremendous amount of money.
Don't discount France for the second round. They will have Zidane back for the game against Denmark, and still only need to win with a couple of goals to go through, regardless of what happens in Uruguay vs. Senegal.
Today we will see what will happen in the Group of Death.
