- Bremer (44')
The hosts got a deserved breakthrough just before half-time when Bremer perfectly timed a run into the box to connect with a cross from Filip Kostic and head the ball into the net.
Both sides struggled to create chances for most of the match but Juventus largely dictated the tempo.
Lazio lacked intensity to challenge a disciplined Juventus defence and never seriously threatened to get an equaliser.
Massimiliano Allegri's side will face Inter Milan in the two-legged semi-finals after they beat Atalanta 1-0.
