Argentina call up uncapped defenders

Argentina coach Alejandro Sabella has named an experimental squad for the friendly matches against Ecuador and Bosnia-Herzegovina later this month.
In a bid to reinforce a defence that has been his side's weak link, Sabella has handed call-ups to Porto's Nicolas Otamendi and Fiorentina's Facundo Roncaglia while also handing Lucas Orban of French side Bordeaux his first call-up.
Argentina will face Ecuador in East Rutherford, New Jersey, on November 15 before taking on the Bosnians in St. Louis, Missouri on November 18.
