Exactly. I was comparing 'talent' as a generalised term rather than a direct comparrison in a positional sense.
Of course Xavi has contributed greatly to the Spanish 'golden' generation. The interesting sample is Xavi's career pre generation 'golden'. That would take him back to the age of 26 or so when he was not considered by a great deal of people to be one of the finest players in the world, in fact, I think that it would be reasonable to say that he was at a similar level to the 24 year old 2012 Samir Nasri.
My overall point being that to take the black and white view of 'Nasri can only dream of being as achieved and integral to an elite teams success as Xavi' as being narrow minded and in my view, incorrect.
