Trophies: 9x La Liga, 6x Copa del Rey, 7x Supercopa de Espana, 4x Champions League, 3x Super Cup, 3x FIFA Club World Cup
Pep Guardiola's comment to Xavi that he would retire him, but Iniesta would retire them both proved to be prophetic, and Barca are now tasked with the challenge of replacing a man who has become the most decorated Spanish footballer in history.
It took time for Iniesta's true genius to be suitably recognised, but there was no doubt when Barcelona's players and fans paid tribute to the great number eight after his final game on Sunday that they fully appreciate just how special a player he was for the club.
Only Xavi has made more appearances for Barcelona than Iniesta, who joined in 1996 and came through La Masia before turning out 674 times for the club across all competitions.
Nine La Liga titles, four Champions Leagues and a host of other trophies have come along the way, in addition to countless great moments - the standout of which at club level is perhaps Iniesta's unforgettable last-gasp goal against Chelsea in the 2008-09 Champions League semi-finals.
Iniesta's demeanour and character has also shone through to help transcend club rivalries - as shown by the midfielder being afforded a standing ovation at almost every ground he has visited during his farewell season, although the admiration for him in Spain is no doubt heightened by his winner in the 2010 World Cup final too.
