If Nery Castillo can't make it back from injury then El Tri have nary a chance. One of the most entertaining matches in the last World Cup was the stage 2 encounter between Argentina and Mexico resulting in a 2-1 defeat that saw the Mexicans almost snatch a draw after they pounded the Argentine goal in the last minutes of that game. So the Argentinians know not to take Mexico lightly.
However El Tri face a rejuvenated Riquelme in blemishless form and without goalpoacher Hernan Crespo out with an injury. Instead, it has been Riquelme, Messi, and suprisingly Javier Mascherano who have come up big. The Argentinians have the complete balance in every department of the game. The Mexicans on the other hand have been very reliant on Castillo whose first touch has been sublime.
If Castillo is out, Argentina should have an easier win, 2-0.
With Castillo, a brace from him is always possible and the Albiceleste will have to up the ante on attack. It will be tight but they should prevail, 3-2.
