BARCELONA left-back Jordi Alba has moved to ease the pressure on his team by claiming it will not be "a failure" if the Catalan giants do not clinch the treble this season.

Luis Enrique's men have already won the Primera Division and are favourites heading into Saturday's Copa del Rey showdown with Athletic Bilbao and next weekend's Champions League final against Juventus in Berlin.

"We are having a very good season and it would not be a failure," Alba said to the Spanish press. "We are two games away from the treble, but I insist it would not be a failure.

"Of course, it would hurt to have reached these two finals and not to win them."

Barca are the only Spanish club to have won a Primera Division, Champions League and Copa del Rey treble, having done so under Pep Guardiola in the 2008-09 campaign.

Alba believe playing Saturday's final at the Nou Camp will prove a big advantage for his team, who will be seeking a 27th domestic cup crown.

"We are playing at home and it's much better to play in our own ground," the 26-year-old said. "It will be a very difficult game but we will go out to win.

"I don't think it's a double-edged sword as we don't have to travel and we know the pitch well."

Alba insists Barca's full focus in on Saturday's final and not on next week's clash with Juve.

"We are concentrating on Saturday's game," Alba said. "And only after that game will be think about the Champions League final.

"We are really looking forward to winning a treble and it would be sad to be distracted heading into Saturday's match.

"This team takes it one match at a time and no-one thinks that Saturday's match will be easy."

Alba, who joined the Catalan club from Valencia in 2012, has started in 45 games for Barca this season.

"It's my best campaign so far," the Spain international said. "When the team plays well we gain confidence and I think I've had a consistent season.

"If I win the next two trophies, that would be huge."

Defeating Italian champions Juventus will be no easy task, according to Alba.

"From a defensive standpoint they are one of the best teams in the world," he said. "But they also have (Fernando) Llorente, (Alvaro) Morata and (Carlos) Tevez up front.

"They are very dangerous and understand each other very well. They are a very difficult team to beat."
