Zinedine Zidane says the dramatic comeback victory over Deportivo La Coruna at the Santiago Bernabeu on 10 December is testament to Real Madrid's strength of character.
Sergio Ramos headed an injury-time winner to give Real a 3-2 win over the visitors and extend their unbeaten run in all competitions to 35 matches — a new club record.
Alvaro Morata opened the scoring early in the second half before Joselu scored twice in quick succession to turn the match on its head. Substitute Mariano Diaz equalised with six minutes left before Ramos's late intervention.
Real struggled to break down their opponents for large parts of the match in the absence of Cristiano Ronaldo and Karim Benzema, who were both rested ahead of next week's Club World Cup in Japan.
"There's something about wearing this shirt and being at this club, it's always been the case," Zidane told the club's official website.
"What we're achieving is down to these players. They've got incredible energy and we know that we're capable of doing big things, just as we've done here tonight.
"You have to believe in yourself and the good thing about this team and this set of players is that they never lose the belief that they can win games in the final minutes."
The win meant Real maintained a six-point lead over Barcelona, who won 3-0 at Osasuna earlier in the day.
Zidane insisted that Real will not get complacent on the back of their club-record 35-match unbeaten run.
"I don't think that we're invincible. One day this run will have come to an end," the Frenchman said.
"The good thing is that the players are aware that, in addition to hard work, having a positive outlook can help us out. Having gone 35 games undefeated gives us strength.
"However, today we were given a hard time, we needed to dig in and we did just that."
