An article from bleacherreport.com positing that Giovani Dos Santos could shine more than Lio Messi at the World Cup has earned attention here. At first glance, this is completely laughable, since Messi is regularly brilliant and Gio has been very good only in flashes (notably, the destruction of a very limited US team in last year's Gold Cup). At the same time, Mexico's group looks better than it is, which could pave the way for "surprising" run, and Gio will be a big part of whatever Mexico does. Messi's problems with Argentina during qualifying, of course, are rather well documented, and expectations are so high that, unless Messi scores a bunch and Argentina reaches at least the semis, people are going to be making negative comparisons to his form at Barca.
It's still a silly article, but Dos Santos being a revelation while Messi disappoints is not inconceivable (especially when you check out the preliminary list of the latter's teammates). But it would be a really depressing result, not unlike your brother's grilled steak sandwich coming out more flavorful than your filet mignon. Nothing against the steak sandwich, but that's not how it's supposed to be.
