#1 Pep Guardiola 2008 - 2012 (14 trophies)
In many people's eyes, the greatest manager of all time. Pep Guardiola was a former Barcelona player and captained the side for many years before departing the club.
He got his coaching licenses upon his retirement, but many scoffed at his appointment as Barcelona coach in 2008, as he had no senior coaching experience, with his only managerial stint coming as coach of Barcelona B whom he managed for just one season.
He went about silencing his doubters in the best possible way, guiding Barcelona to its first ever treble in 2009 and taking it a step further by becoming the first club to win all six trophies available in a calendar year.
A steep student of Cruyff, Guardiola studied the Dutchman's methods and instilled a possession-based style of play on his team which is fondly called tiki-taka which was so successful for so long that opposing teams found it hard to come up with a solution. Till date, his Barca team is widely regarded as one of the best club sides in football history.
He helped bring out the best in Lionel Messi, having identified him as a special talent at a young age and making the decision to build the team around him which reaped immense benefits.
Pep departed Barcelona in 2012 having won a mindboggling 14 trophies from a possible 18 in four years and remains the most successful coach in Barcelona's history.
