“An interesting battle between formations and an excellent match ended with a narrow Barcelona win. Max Allegri went for his usual system, Kevin-Prince Boateng shuttling from midfield to link up with the front two, with Robinho starting rather than Pato. Alberto Aquilani started on the right of midfield. Pep Guardiola was without a host of players including both Dani Alves and Adriano, and went for his system featuring a back three, and a diamond in midfield. Barcelona had more of the ball (of course) and created more goalscoring opportunities, but were never completely in control of the game.” Zonal Marking
