i would bet on argentina is juan roman riquelme was in the squad

you would have lost. Diabolical squad selection by Maradona, as feared:

Agüero, Sebastián Blanco, Andújar, Bolatti, Burdisso, Coloccini, Dátolo, Demichelis, Di María, Garcé, Jonás Gutiérrez, Heinze, Higuaín, Insaurralde, Lavezzi, Mascherano, Mercier, Messi, Diego Milito, Otamendi, Palermo, Pastore, Pozo, Clemente, Maxi Rodríguez, Romero, Samuel, Sosa, Tevez and Verón

who did he leave out that he should have picked?

i understand he had an argument with riquelme which forced riquelme out of the team.
