"Despite everyone's best efforts, the club has failed to achieve any of its stated targets this year, with the exception of qualification for next season's Uefa Champions League. This, combined with an identified need to develop a holistic approach to all aspects of football at the club, has meant that the decision has been taken to find a new manager for the 2013-14 season and beyond."
The reference to a "holistic approach" suggests a sea change in philosophy from top to bottom of the club, driven by the chief executive, Ferran Soriano, and Txiki Begiristain, the director of football. This may include playing 4-3-3 throughout the academy and in the first team. Following the removal of Mancini, who could be a divisive figure, there may also be a hope that the club will be more cohesive.
