The wing-back has inked a contract with the Biancocelesti and will continue his career in Serie A after struggling to for first team action in Portugal
The Serie A outfit were keen to add some more depth to their squad this winter, and head coach Vladimir Petkovic sees the 24-year-old midfielder, who can also operate at right-back, as a useful addition to his roster.
Pereirinha is a product of the illustrious Sporting youth academy, but never really managed to secure regular first team action at the Lisbon giants. Therefore, he has now opted to move on in an attempt to relaunch his career at Lazio.
The former Portugal Under-21 international has reportedly signed a contract with the Stadio Olimpico side until June 2016, and could make his official debut in this weekend's Serie A match against Genoa.
