Real Madrid assistant Aitor Karanka praised the work-rate if his players after they defeated Barcelona 2-1 on Saturday.
Goals from Karim Benzema and Sergio Ramos were enough to give Los Blancos the three points at Santiago Bernabeu.
And the 39-year-old has insisted that they now go into their Champions League clash with Manchester United full of confidence.
“This win makes us stronger,” he told a Press conference. “I am happy with the performance of all the players – which is needed in these types of matches.
“We started with some players that don't normally start, and you have to be pleased with how they played.
“We have confirmed what we already knew – we can rely on all of the players in this squad.
“The past five days have made us happy, but now we have to train hard and prepare for the match against Manchester United.”
