Lazio president Claudio Lotito is confident Juan Pablo Carrizo will gain his European passport.
The Argentine goalkeeper is battling to gain an Italian passport and Lotito declared: "I assure you that Carrizo will become a European and he will be one of the two goalkeepers we will count on.
"Carrizo will get his passport because he has everything legal and in place. But in the meantime, we have signed another young goalkeeper of equal quality."
Lotito was referring to Fernando Muslera, who arrived in Rome last week from Nacional de Montevideo.
