In the last decade, the dominance of FC Barcelona has been clear. They have claimed four Champions League crowns, six league titles and three cups. With Argentinean Leo Messi claiming the World’s Best Player award four times in the last six years, they also have the player of the decade. Despite all this success, the team stumbled in the 2013/14 season and didn’t claim any major trophy. Incredibly, in the following season, Barca was virtually unstoppable and won its second treble or clean sweep - the only club in history to achieve this feat twice. So what changed between the seasons? What did the staff, coaches and club do behind the scenes to reignite the fire? What’s the secret behind their turnaround? Barca had to reinvent itself from the inside out, and it all started in the locker room. Learn the behind-the-curtains story straight from the mouths of Leo Messi, Gerard Pique, Luis Suarez, Javier Mascherano, Ivan Rakitic, Juliano Belletti and Dr. Dani Medina.
