barcelona

definitely a legend:
messi
iniesta
xavi
valdes
puyol
david villa

probably a legend:
neymar

dani alves
busquets(if he is a good player)

if you want to know why, it's because barca keep players for a long time and real madrid sell and buy and replace every year.

If this list is for current players then why the heck is Puyol up there...

coz puyol still is not with legends
