Pedro has revealed that morale in the Barcelona camp is low after their 3-2 defeat to Osasuna.
With his team trailing by two goals after an ineffectual first period, the winger was replaced at half-time by Cristian Tello, who scored and made an assist after the break.
The result leaves the Catalonians 7 points behind Real Madrid, who play Levante on Sunday evening.
Speaking after the game, Pedro said: "We're saddened by how the game has gone. We're unhappy.
"We struggled to get into the game and Osasuna came out of it the strongest. We should have been able to overcome them, but ultimately we could not."
Pedro has made 15 La Liga appearances this season, scoring once.
