The Real Madrid defender believes la Roja were bound to lose a big game at some point as no team can keep on winning
Vicente del Bosque's men had dominated international football in recent years as they won back-to-back European titles as well as the 2010 World Cup, but their trophy haul came to an abrupt end at the Maracana on Sunday.
"We have gained a lot of important achievements and one day, the moment has to arrive when you don’t win. We aren’t machines. Our conscience is clear because we gave the best we had," the defender told AS.
"Sometimes things just don’t turn out for you and that is what happened to us right from the first minute. They got an early goal and then withdrew.
"We must congratulate Brazil because they showed that they know how to play against Spain."
Spain had to settle for third spot the last time they featured at the Confederations Cup in 2009.
