Amad Diallo keeps coming up with big late goals for Manchester United. There were three of them on Thursday in a remarkable 12-minute flurry that rescued United from an embarrassing loss to the Premier League’s worst team.

Diallo, a 22-year-old winger from the Ivory Coast, scored a hat-trick from the 82nd minute to earn United a 3-1 victory over last-place Southampton, just when it looked like his team were heading for a fourth straight home loss for the first time since the 1930s.
