Vicente del Bosque's side got their Euro 2016 qualifying campaign off to a convincing start on Monday, though, with a 5-1 rout of Macedonia in Valencia.
Silva netted the fourth of his side's goals, and the Manchester City man insists he and his team-mates can not worry about how others perceive them.
"We have to learn to live with the criticism," he said.
"At the very least there are always doubts and at this level we have to accept that, but we always try to do our best.
