Barcelona manager Xavi maintains his side are “closer to success than defeat” as they look to avoid an upset in their Copa del Rey last-16 tie at third-tier Unionistas.

A 4-1 defeat by rivals Real Madrid in the final of the Spanish Super Cup on Sunday further increased the pressure on Xavi and his squad.

Bara president Joan Laporta and other members of the board visited the training ground on Wednesday in an attempt to lift spirits in the camp.

Unionistas, the only non-professional team left in the tournament, secured a place in the last 16 with a penalty shootout win over Villarreal, the initial tie having been suspended following a floodlight failure and finished the following day.

The trip to Salamanca is set to further test Barca’s ambitions, but Xavi insists there is plenty left for the team to play for this season, both domestically and in Europe.

“I am here because I have achieved certain targets. When I joined they told me the goal was to finish fourth and we finished second,” Xavi said at a press conference.

“Last season the goal was to win the league – and we did that and also won the Super Cup, surpassing expectations.

“The goal this year was to win trophies and we are halfway through the season and the three most important ones are all still to play for. We are closer to success than defeat.”

Barcelona will be without defender Ronald Araujo following his dismissal against Real, while teenage forward Lamine Yamal is suspended following a red card in the Youth Copa del Rey last year against Malaga.

After seeing his side taken apart at the back by Real, with Vinicius Junior scoring a first-half hat-trick, Xavi knows his side have to tighten up.

“We have to improve in defence. We can’t let in so many goals or make things easy for the opposition,” he said.

Xavi is expecting a hot reception at the Estadio Municipal Reina Sofia as they look to secure a spot in the quarter-finals.

“They are good in the air, play direct football and have very clear ideas,” he said. “It won’t be an easy place to go – for them it is the biggest game of their lives.”

Unionistas play in the Primera Federacion alongside Barcelona’s reserve team, running out 2-0 winners against Rafael Marquez’s side at the Estadi Johan Cruyff earlier in January.

Manager Dani Ponz knows his men will be underdogs on Thursday night but is relishing the contest against one of Spain’s giants.

“We cannot be intimidated. It is impossible to stop a team like Barcelona, but we cannot fall into disbelief,” Ponz said at a press conference.

“We are going to continue playing the same way – always looking forward.”
