The Blaugrana fell to their second straight away defeat in La Liga but their coach is insistent his side can still retain the league crown
Barcelona coach Gerardo Martino remained defiant about his team's title hopes after a dismal 1-0 defeat at Real Valladolid on Saturday.
The champions slumped to a second consecutive away Liga defeat, with Fausto Rossi pouncing on a ricochet to net the game's only goal 17 minutes in.
Lionel Messi saw a host of chances saved by Valladolid keeper Diego Marino, while Neymar missed a great opportunity in the second half as Barca was consigned to its fourth league loss of the season.
The result leaves the Catalans one point behind leader Real Madrid at the top of the table, with Carlo Ancelotti's men hosting Levante on Sunday, but Martino is refusing to write off his team's chances of retaining its crown.
"While we still have a chance mathematically, we will keep fighting for the title," the Argentinian said.
"We struggled with our mobility, especially in the final 20 meters of the pitch. We couldn’t find the space. We had a lot of the ball, but lacked any depth.
"It is clear from today that we are not at our best. And we need to be at our best against Real Madrid."
Midfielder Xavi was under no illusions about how poor the result and performance were, admitting that he could see no plus points.
He told Carrusel Deportivo: "We can't draw any positive conclusions from that result and performance.
"We have to try and improve ahead of Wednesday (against Manchester City in the UEFA Champions League).
"It just wasn’t to be today. It's a very painful loss - definitely a step back for us."
