Real Madrid set a new club record after a 35th consecutive match without a loss by beating Deportivo la Coruna 3-2 on another Sergio Ramos stoppage-time winner on Saturday.
Ramos, who scored an injury-time equaliser at Barcelona in the last round, headed in a corner kick after 90 minutes were up to maintain Madrid's six-point lead over Barcelona atop the Spanish league.
"You fight until the very end, with faith, with enthusiasm, with commitment, and things go your way," Ramos said.
Madrid appeared to have the milestone well in hand after Alvaro Morata gave the hosts the lead with a strike from distance, but former Madrid youth player Joselu Sanmartin went on for Deportivo and scored twice in a three-minute span to force Madrid into fight-back mode.
With Cristiano Ronaldo and several other first-choice players unavailable, Madrid needed little-used Mariano to level at 2-2 in the 84th before Ramos snatched the winner.
Under coach Zinedine Zidane, Madrid hasn't lost since April 6 when it fell 2-0 at German side Wolfsburg in the Champions league knockout rounds. Madrid recovered from that setback to win its record 11th European Cup.
The previous unbeaten streak for the club founded in 1902 was 34 games in 1989, set by a side coached by leo Beenhakker. Barcelona holds the unbeaten mark for all Spanish clubs of 39 games which Madrid ended last season.
Zidane said this winning spirit formed part of the club's identity.
