In the summer of 2011, Arsenal fell into its darkest moment: captain Cesc Fabregas "defected" Barcelona, and the ridicule of "selling the captain" and "fighting for the top four" swept the UK. The fate of 17-year-old Karen Brady, a youth training youngster who was supposed to be a defender, was changed by Wenger's words: "I want to be an ordinary defender or a world-class midfielder." No one paid much attention to his arrival, but he has to carry the hope of the team's revival amidst the doubts at the Emirates Stadium. The perseverance of middle-aged fan Dave, the expectations of young Liam, and Wenger's trust hidden under the white hair, all turned into the strength at Karen's feet - when the red and white jersey is raised, can this boy break the curse of the "temperature difference sign" and bring the sunken arsenal back to its peak?
