#4 Andres Iniesta
Another player who came through La Masia, Barcelona's youth academy, is Andres Iniesta. He made his first-team debut at 18 years old in 2002 and was picked regularly for the team during the 2004/05 season, and from there, became a key first team player until his departure in 2018.
Iniesta was a pivotal player in the side that won the two historic trebles in 2009 and 2015. The Spaniard also won a staggering nine La Liga titles and four UEFA Champions League titles, which makes him the most decorated Spanish footballer of all time.
There could be no doubt about his inclusion on this list as Iniesta was one of the most influential players in the Barcelona squad throughout the noughties and much of the 2010s.
He now plays for Japanese side Vissel Kobe, who he joined on a free transfer once his contract expired with Barcelona.
