Probable starting eleven:

Greece:

Romero, Otamendi, Demichelis, Burdisso, C. Rodriguez; Maxi Rodriguez, Bolatti, Veron; Messi; Milito, Aguero

Argentina:

Tzorvas, Vyntra, Papastathopoulos, Papadopoulos, Kyrgiakos, Torosidis; Tziolis, Katsouranis, Karagounis; Salpingidis, Gekas

The crucial game for Greece. They must win if they want to progress. Many things also depend from other game between Nigeria and South Korea, but since they are playing at the same time, Greece have no other option then to attack. And attacking Argentina is something like suicide. So, I think Over 2,5 goals is the best option on this match. Maradona will probably play with second strikers duo. Somebody might think it is handicap for Argentina, but wait. Milito and Sergio Aguero are top class strikers. While other coaches have a "real problem" with the strikers, Maradona have "sweet problems" with his strikers. Tevez, Higuain, Milito, Aguero, they are all first class strikers and whoever start the game it is the same. On other side Argentina defense will be without suspended Jonas Gutierrez. It is expected Nicolas Otamendi to replace him at right back position and i think it is a small handicap for Argentina.

At the end I will mention that three out of last four Argentina games ended with lot of goals. Just look:

Argentina 4-1 South Korea
Argentina 1-0 Nigeria
Argentina 5-0 Canada
Argentina 4-0 Haiti

Greece isn't so efficient, but their last game against Nigeria finished with 2:1. Considering there is no space for calculations, i am sure Otto Rehhagel will play open and that guarantees goals.
