Bayern were dealt another blow with a half-hour to play when Javi Martinez was sent off for a second yellow card within three minutes for fouls on Ronaldo.
Real pressed home the numerical advantage as Ronaldo tapped the ball between the legs of Bayern's goalkeeper Manuel Neuer for the victor on 77 minutes.

The Real coach said his side were lucky to have only been a goal down at the break after Vidal's penalty miss.
