Zinedine Zidane's Real Madrid have already made club history by going 35 games unbeaten, but now Los Blancos have the 39-game unbeaten run of fierce rivals Barcelona in their sights.
The current run began after April 4, when the team picked up their last defeat - in the UEFA Champions League against Wolfsburg.
Eight months later the victory over Deportivo La Coruna means that Real have surpassed the previous record of 34 games unbeated, established by the Madrid of the Quinta del Buitre in 1988/89 when Leo Beenhakker was on the bench.
It's been a sensational streak that has included 26 victories and nine draws and one that Zidane and Co. hope that they can continue in Japan at the Club World Cup.
Luis Enrique's Barcelona went on their run last season and if Real manage to surpass that mark, there will only be two rivals left to overcome.
Nottingham Forest's 40 unbeaten games achieved between 1977 and 1978 and Antonio Conte's absolute record of 43 matches with Juventus, which he managed between 2010 and 2011.
Zidane's side have to return from Japan with the CWC title and then remain undefeated in the next two matches to catch the Catalans.
