Following the departure of Lazio first-team starting goalkeeper Juan Pablo Carrizo to Internazionale, in the second half of the 2012–13 season, Strakosha gained entry with the first team as third-choice goalkeeper, behind Federico Marchetti and Albano Bizzarri. He was member of the team that won 2012–13 Coppa Italia after defeating city rivals Roma 0–1 in the final on 26 May 2013. On 18 August 2013, Strakosha was again on the substitutes' bench as Lazio lost 4–0 to Juventus in the 2013 Supercoppa Italiana.
