Barcelona's young players, lead by teenage sensation Gavi, were at the heart of the club's first trophy for nearly two years as they thumped rivals Real Madrid in the Spanish Super Cup.Gavi, 18, scored and fashioned two more in their 3-1 victory on Sunday, including one for 20-year-old Pedri, while defender Ronald Araujo shackled Vinicius Junior and Alejandro Balde excelled on the other flank."A new era has started," yelled an ecstatic Araujo as he ran back to the dressing room with his medal, after wild celebrations on the pitch in Saudi Arabia.The ushering in of a new start for Barcelona is the club's fervent hope, after they lifted their first trophy in the 21st century without Lionel Messi being part of the squad.When the Argentine icon left for Paris Saint-Germain in 2021 after spending his whole career at the club, it shook Barca and the football world.Deluged by debt, the Catalans spent big in the summer, a spree funded by mortgaging part of their future television income, among other methods.They signed Robert Lewandowski, who also netted against Madrid in the Super Cup triumph in Saudi Arabia, as well as Jules Kounde and Raphinha among others.Gradually the Barcelona team which conquered Europe in 2009, 2011 and 2015 is being dismantled, with only a couple of veterans remaining.Xavi was one of the first to depart, leaving on top of the world after winning the treble in 2015, and now he has been working on reshaping a club which president Joan Laporta said was "almost dead" when he took over.There is a young core to Xavi's team, with Gavi and Pedri key to the reshaped midfield, while Araujo and Kounde are in their early 20s.Balde, 19, has displaced veteran Jordi Alba at left-back more often than not this season,
