Lazio hero Angelo Peruzzi believes his old team's goalkeeper problems are down to the failure to secure a European passport for River Plate's Juan Pablo Carrizo.
Peruzzi said: "The problems are due to the non-signing of Carrizo. They signed a young goalie like Fernando Muslera, but he had no experience in a championship as hard as ours.
"Then there is Marco Ballotta, who despite some injuries, always does well season after season."
