There are questions about Argentina heading into the World Cup opener:

Will a three man backline with Jonas moving in and out of the right-back position work against a team like Nigeria that can launch fast, counterattacks?

New starting backline against Mexico.

Maradona confirmed in yesterday's press conference that Burdisso will replace Samuel in the lineup because Samuel is not 100% fit.

Maradona did not confirm the rest of the starting lineup.

The speculation in the Argentina media is that this will be the starting eleven against Mexico today:

Romero

Otamendi-Demichelis-Burdisso-Heinze

Maxi Rodriguez-Mascherano-Di Maria

Messi-Higuain-Tevez

Needless to say, a very important game today.
