Barcelona manager Luis Enrique insists his players will “fight until the end” in both their La Liga and Champions League campaigns after seeing off Real Sociedad 3-2 at the Nou Camp to stay within striking distance of Real Madrid ahead of El Classico.

The pressure was firmly on Barca after their rivals had earlier beaten Sporting Gijon with a late goal from Isco as Enrique’s side looked to avoid a third straight defeat.

Lionel Messi drilled in the opening goal from 25 yards after 17 minutes and then added a somewhat fortunate second when the ball bounced in off his leg from a rebound.

Sociedad reduced the deficit through an own goal by Barcelona defender Samuel Umtiti only for Paco Alcacer to quickly restore the home side’s advantage.

Although Xabi Prieto’s strike in first-half stoppage time set up a tense second period, it was Enrique’s men who eventually came through.

Barca must now quickly focus attentions on how to overturn a 3-0 deficit against Juventus in the second leg of the Champions League quarter-final before the small matter of a trip to Santiago Bernabeu on April 23.

“We will fight until the end,” Enrique said at the Barcelona post-match press conference.

“This win is a good starting point for the return leg of the quarter-finals of the Champions League.

“We need the players to be confident and to improve in certain aspects.”

The Barcelona boss added: “We go into the Champions League and El Clasico alive. I have seen my players prepared for any situation and we put in a huge effort. We were able to get a result against a really tough opponent who were perfectly organised.

“I take away the irreproachable attitude of my team. We have deserved the win even though it was difficult for us.”

Defender Gerard Pique believes Barcelona can still meet their goals this season, both in Europe and LaLiga.

“They are two games that if we win, the whole feeling (within the squad) will change,” he told reporters.

“With the team we have, it is possible to turn everything around.”
