Barcelona boss Luis Enrique has called on the club's supporters to back their team against Valencia in La Liga next weekend.
The Catalan outfit have lost their last two in the league, including a 1-0 defeat at Real Sociedad on Saturday, which has allowed Atletico Madrid and Real Madrid to move within three and four points respectively of the leaders in Spain's top flight.
Enrique has insisted that his team 'never believed that the league was already won' and has backed his players to answer their critics when they host Valencia on Sunday night.
"On Saturday, I need all the Catalans at the stadium to help us against Valencia. We never said it was easy, that the league was won or anything," Enrique told reporters.
"It's a wonderful opportunity to demonstrate that we're the best team in the world. I have no doubt that we'll compete. It's evidence [that there's less margin for error now]. Three weeks ago we were in a much more comfortable situation."
Barcelona will travel to Atletico for the second leg of their Champions League quarter-final on Wednesday night.
