Manchester United manager Jose Mourinho said "being good defensively is not a crime" as his side edged past Benfica in the Champions League.
The only goal of the game in Lisbon came courtesy of Marcus Rashford's long-range free-kick which caught out teenage goalkeeper Mile Svilar on his European debut.
Belgian Svilar, the competition's youngest goalkeeper at 18 years and 52 days, had a moment to forget when he carried Rashford's 35-yard free-kick from out wide over his own goalline.
Rashford gave United a cause for concern when he limped off with a knee injury in the second half and was replaced by Anthony Martial.
United were criticised for their approach in their goalless draw against Liverpool on Saturday in which they hit the target just once, but the Red Devils have now conceded just six goals all season.
