Danger is lurking for Lionel Messi's Barcelona. And its name is Liverpool. The front page of Tuesday's edition of Mundo Deportivo, which is one of Catalonia's two daily sports newspapers, runs with an alarming headline, "Code Red", alongside a picture of Liverpool's coach Jurgen Klopp instructing Mo Salah about his lines of battle.
Mundo Deportivo lays out Liverpool's numerous strengths: Klopp's charisma; the class of Salah and Roberto Firmino up front; Sadio Mane and Virgil van Dijk's impressive form; Liverpool's "asphyxiating" high-press; their ability to generate danger without the ball and to effectively execute their strategy.
