Barcelona coach Xavi Hernandez said on Monday that his time as a player helped set a high standard that the club is now struggling to meet in the Champions League.
Between 2006 and 2015, the Catalan giants won four editions of the championship, but have subsequently suffered some humbling eliminations.
Barcelona has recently let leads against Roma and Liverpool slip and been hammered by Bayern Munich, while they have failed to advance past the group stage in the previous two seasons.
“There is huge demand on us, the bar is so high — this is Barca,” Xavi told a news conference.
“This is a consequence of the Barca of the past few years, of our era, as a player. In 10 years, from 2006 to 2015, four Champions Leagues were won.”
The coach said the club’s objective was to make it through the group phase, ahead of their opener in the competition against Belgian champions Royal Antwerp on Tuesday.
“We like challenges, but the level of demand is so high, it’s brutal,” he continued.
“It’s a consequence of inheriting a brilliant era, the best in the history of this club.”
However Xavi said his players were coping well and excited to start their new European campaign.
“Looking in the faces of the players, the joy, I see hope,” added Xavi. “A lot of hope and desire.”
Barcelona spent little in the summer as they continue to endure financial difficulties, but were able to sign Joao Felix and Joao Cancelo on loan.
They also replaced Sergio Busquets with former Barca youth team product Oriol Romeu, signed from Girona.
The midfielder, 31, said he did not imagine he would be back at this level after leaving Barcelona in 2011 for Chelsea, later joining Southampton in 2015.
“I’d be lying to you if I said that when you go to Southampton you think you’ll be playing a key role at Barcelona (one day), it’s hard to imagine,” said Romeu.
“Football has many twists and turns. I’m happy, and hopeful of doing a good job.”
