When Gareth Bale scored from a towering second-half header against Villarreal, Real Madrid had managed to equal a record set 73 years ago by arch rivals Barcelona.
Los Blancos have now registered in 44 consecutive games, a run which began after a goalless draw in the Champions League semi-finals against Manchester City on 24 April, 2016.
The Catalans had set their record between 1942/43 and 1943/44, a period in which only LaLiga and the Copa del Rey were competed for.
Barcelona lost 11-1 to Real Madrid in the cup, the biggest defeat in their history, and the streak in the league ended with a 2-0 defeat against Granada.
