#1 Luis Enrique
After a disappointing spell at AS Roma, Luis Enrique returned home to manage Celta Vigo and the Spanish side had a brilliant run under him, managing to finish ninth in the league table with limited resources.
Enrique's side played fluent football and with his Barca DNA, he was named as the next Blaugrana manager. What followed next was a spell of immeasurable success, the first since Pep Guardiola's unmatched sextuple winning season.
Under Enrique, Barcelona won the treble in 2015. They also managed to claim the league title for two successive years and are the Copa Del Rey holders since 2015.
Though his departure from the club was celebrated by a few Barcelona fans, he is perhaps not given enough credit as many claim he had the 'MSN' doing all the work for him on the pitch. Regardless, he is still a manager man top clubs will look at.
