Trophies: 2x La Liga, 2x Supercopa de Espana, 1x Champions League
Ronaldinho's appearance tally, goal record and trophy haul may not stand up against others on this list, but his impact and influence on Barcelona goes far beyond statistics.
The Brazilian's arrival from Paris Saint-Germain came at a time when Barca had finished outside the top three in three successive seasons - including a sixth-placed finish in the campaign immediately prior to Ronaldinho joining, their joint-lowest league position since 1941-42.
It didn't take long for his infectious style and smile to spread throughout the Camp Nou, and he helped end the barren years by winning two La Liga titles and the 2006 Champions League during his time at the club.
Ronaldinho's legacy is defined by his play rather than his trophy cabinet, though, and there are plenty who consider the Brazilian to have been among the greatest of all time at his peak - and certainly one of the most entertaining players to have ever played the game.
That peak did not last quite as long as it might have due to his off-field interests, but he still left an enduring mark on the club and even assisted Lionel Messi's first Barcelona goal - an iconic passing of the torch which saw his number 10 shirt taken to new heights.
