From 20:00, at Estádio da Luz, the national champions will not only look for their first win but also for their first points, as their disastrous entry into Group D, with defeats against Salzburg (2-0), at home, and Inter Milan (1-0), away, leave the team led by Roger Schmidt in last position of the group.
Real Sociedad and Inter are ahead, both with four points, followed by Salzburg, with three, so a new defeat for Benfica against the San Sebastián team, and a victory for the Italians against the Austrians, will practically rule out the chances of Benfica's qualification for the next round.
At the same time, Sporting de Braga will receive Real Madrid, record holder for trophies in the main European club competition (14), with the Portuguese team reaching this third round with three points in Group C, equal with Napoli and three fewer than the Merengues, who are in first place. In last place, Union Berlin follows, with no points.
