Before the tournament started, I would have said Argentina was one of the favorites after all, they won the last one after all. After seeing some of the favorites get off to a slow start, I'd say their chances look even better. And after seeing Messi, despite currently playing in what many would call a "recreational" league, still looking sharp, I'd say teams like France and England (the ones that have played at a very high level against strong opposition) will have their work cut out for them. So yes, I believe Argentina can do it, and I wouldn't be surprised at all if they did.
