Lionel Messi, Angel Di Maria, Gonzalo Higuain and Fabricio Coloccini were named in the 22-man squad Alejandro Sabella originally assembled, though that number has now increased to 24 with players who ply their trade in the Primera Division.
Velez Sarsfield midfielder Cerro, 25, currently has just one senior cap to his name for the Albiceleste, though this was playing in a squad comprised entirely of footballers who ply their trade in South America against Brazil.
Newell's Old Boys attacker Maxi has a much more impressive international resume, having featured for Argentina at the last two World Cups and made his debut over a decade ago.
The 32-year-old is long past his heyday, when he impressed for the likes of Atletico Madrid and Liverpool, but he has impressed for his club side this season, including scoring the winning penalty in his side's Copa Libertadores quarter-final.
The clash will be played on Wednesday at the Stadio Olimpico in Rome, having been arranged following an Argentine - Jorge Mario Bergoglio - being named the new head of the Catholic Church earlier in 2013.
