Lewis Dunk’s unfortunate own goal, deflecting in an Ashley Young shot, sealed a 1-0 win for Manchester United over Brighton & Hove Albion.
Young’s drive from the edge of the area hit the Brighton defender and looped over goalkeeper Mat Ryan for the only goal in the 66th minute.
Ryan had kept Brighton in the match right on half-time with a double save from Romelu Lukaku and Paul Pogba.
Brighton had matched United, threatening on numerous occasions with dangerous crosses from Anthony Knockaert and Pascal Gross, and Shane Duffy heading narrowly wide.
United go five points behind leaders Manchester City, who play Huddersfield Town on Sunday.
Brighton’s first league defeat in six matches leaves them ninth.
