ROME - Juventus secured the first part of a possible domestic and European treble with an efficient display against Lazio in the Coppa Italia final.
Juve went ahead when Dani Alves's side-footed volley bounced into the corner. Leonardo Bonucci sealed victory when he prodded in and Lazio, playing in their own stadium, could not find a way back.
This Serie A leaders can clinch their sixth successive Scudetto this weekend and meet Real Madrid in the Champions League final on 3 June in Cardiff.
Massimiliano Allegri's side settled the match in the opening 25 minutes as they became the first side to win the competition three times in a row. Lazio were competing in their third final in five years, hoping to inflict a measure of revenge after Juve beat them 2-1 after extra-time in 2015.
The capital club have not won another major honour since they beat neighbours Roma in 2013, with manager Simone Inzaghi prioritising the final by resting several key players for Saturday's 3-2 defeat at Fiorentina.
The fourth-placed Serie A side, who are 15 points behind leaders Juve, made an energetic start and saw young striker Keita Balde Diao hit the post early on.
They created more chances after the break as Felipe Anderson and Ciro Immobile drew superb saves from Gianluigi Buffon's understudy Neto, but by that time Juve had already done enough to seal victory.
