Barcelona coach Hansi Flick insists his team requires more than just Lamine Yamal to overturn a 4-0 first-leg deficit against Atlético Madrid in the Copa del Rey semifinal. The 18-year-old striker scored his first career hattrick against Villarreal but Flick emphasizes collective effort is crucial. 'We need everyone,' he stated, highlighting the unprecedented nature of the challenge. 'It's not only Lamine, we need everyone on the pitch.' Barcelona's last 4-0 Champions League win over Borussia Dortmund serves as Flick's blueprint for the impossible turnaround, though the return of Robert Lewandowski (eye socket fracture) and Pedri (from injury) offers limited relief against Atlético's threat. Yamal's performance after scoring Saturday was 'great to see,' but Flick warns, 'We know it's difficult. They hurt us a lot in the last match.' The return game at Camp Nou on Tuesday demands Barcelona play with 'hunger' and 'intensity' to score at least two goals per half and 'make the impossible possible.'
