Barcelona head coach Xavi says Sunday's 1-0 win at Alaves shows that there is life in the Blaugrana yet.
Frenkie de Jong netted an 88th-minute winner to clinch the points for Xavi's side, who move up to fifth in LaLiga, one point behind fourth-placed Atletico Madrid.
Barcelona bossed possession (76-24 percent) and generated 10-6 shots with 4-2 on target, getting their just reward with the Dutchman's late goal.
"It cost us a lot, but they were three crucial points and the team needed and deserved them," Xavi told reporters. "The sun has risen again, this victory shows that there is life."
He added: "It means a lot of confidence, continuing to believe in what we do."
Barcelona will enjoy a break before their next league game against Spanish champions Atletico Madrid on Sunday 6 February.
“We are in the fight, one point away from the Champions League," Xavi said. "These days are going to come in handy. They will come in very handy."
The Barcelona boss was also complimentary towards teenager Pedri, who has only just returned to the fold following a thigh injury. Pedri made his first LaLiga start since August.
"He’s a marvellous little player, and at 19, to do everything well is spectacular," Xavi said.
"How he looks in possession, how he perceives the game, he is excellent and the model player. He can lead by character, quality, ambition, it’s great to have him back in the team."
