#1 Ronaldinho
Ronaldinho Gaucho, what can we say about this man that hasn't been said before. His artistry on the football pitch brought a smile to more faces than we could imagine. For Barcelona, however, he was much more than a world-class footballer, he was their angel, their saviour.
Barcelona had gone four straight seasons trophyless, agonising in mid-table mediocrity when a 23-year-old Ronaldinho joined them from PSG. With him at its forefront, the club rose from ashes like a phoenix.
In the next three years, Barcelona went from playing in UEFA Cup to winning consecutive league titles and the 2006 UEFA Champions League. For his brilliant performance throughout the period, Ronaldinho won the Ballon d'Or in 2005 and FIFA World Player of the Year in 2004 and 2005.
Unable to find room in Pep Guardiola's new Barcelona, Ronaldinho left for AC Milan in 2008. What he left behind was a vast legacy and a successor in the form of his protege, Lionel Messi.
Ronaldinho may not have had a debut season as remarkable as Ronaldo Nazario or a career as decorated as Dani Alves. But he was pivotal in laying a strong foundation that allowed Barcelona's ascent to the absolute top. And for this reason, we consider him the greatest Brazilian footballer in the club's history.
