Two goals from Luis Alberto helped Lazio earn a 3-0 victory over third-placed AS Roma in the city derby on Friday, with Simone Inzaghi's side up to seventh after a third Serie A win in a row. Lazio made a lightning start and went ahead after 14 minutes, with Ciro Immobile capitalising on a woeful error from Roger Ibanez to score his 12th league goal of the season. Roma looked stunned as Lazio kept committing plenty of players forward, and the pressure told as Luis Alberto swept home a well-taken second in the 23rd to double the advantage.
