1. FC Barcelona
In first place is FC Barcelona with their luxurious home grown squad.
Barcelona are no doubt the greatest club to produce talent, with the likes of Xavi Hernandez, Gerard Pique, Andres Iniesta, Sergio Busquets, Pedro Rodriguez and Lionel Messi.
All the above mentioned have gone on to make massive names for themselves at the Nou Camp, with nearly all of them earning themselves a legend status.
Yes Pique left to join Manchester United and then came back, but at United he wasn’t the player he is now at Barca, so that will have to go down to the Spanish giants.
You could also mention Cesc Fabregas who was at their youth set-up, however, he certainly made his name when he was at Arsenal before returning to Barca years later.
