#9 Dani Alves
Dani Alves kickstarted the Pep Guardiola era when he was made the first signing of the 2008/2009 season, arriving from Sevilla for the sum of £31m in July 2008.
He had an immediate impact, seamlessly easing into the complex tactical demands Guardiola makes of his full-backs, while his explosive runs forward and pristine deliveries were a crucial part of Barcelona's attacking arsenal.
The Brazilian developed an on-field and almost telepathic relationship with Lionel Messi and for many years, he held the record as the player with the most assists for the Argentine until he was recently overtaken by Luis Suarez.
In total, he made 391 appearances for Barcelona in eight seasons, scoring 21 goals and creating an unbelievable 100 assists, while he also won 23 major trophies including two continental trebles.
He left Barcelona for Juventus in 2016 and added to his impressive medal haul with a further spell at PSG.
Despite turning 36 last May, he returned home to Sao Paolo after he captained Brazil to Copa America success on home soil last summer.
With over 40 major honours won at both club and international level, Alves is currently the most decorated footballer in football history.
