Benfica are 45 minutes away from the Europa League final after a goalless first half away to Juventus in their semi-final second leg.
Andrea Pirlo went close for the home side when he latched on to the ball on the edge of the box before his effort was well saved by Benfica goalkeeper Artur.
Arturo Vidal then struck a powerful volley on 19 minutes, but the Chilean midfielder's effort was too high to trouble the goal.
Carlos Tevez was next to try his luck for the Bianconeri, but his volley inside the area was again too high, before Paul Pogba scuffed a long-range shot wide.
Leonardo Bonucci spurned another chance for Juve when he headed Pirlo's free kick wide towards the end of the half.
It was Vidal's chance at the death which came closest however, but this time, his header was cleared off the line in first-half stoppage time.
