Real Madrid beat Atletico Madrid in a Champions League penalty shootout — again — to keep its title defense alive Wednesday and advance to the quarterfinals.

Atletico midfielder Conor Gallagher had scored the only goal of the game in the opening minute to draw the tie level on aggregate at Metropolitano Stadium in Madrid, Spain. Real are second in LaLiga but level on points with leaders Barcelona. Atletico are third – just a point behind the top two.
