When Luis Enrique took the Barcelona job in May 2014, the club were still very much stuck in the Pep Guardiola way of playing.
It's not exactly a bad system to be stuck in. Guardiola is the most successful Barcelona boss in recent history but when he left the club in June 2012, it took a while for the La Liga giants to form a new identity once again.
Tito Vilanova and Gerardo Martino both had short spells post-Pep and before Enrique, but neither stayed around long enough to create a new way of playing in Catalonia. It was up to Enrique to do what seemed like a really difficult job. Get Barcelona playing the best football once again while being successful in doing so and standing out from what we saw at the Nou Camp under Guardiola.
