this is not the place to discuss whether Catalonia is a nation (as some say) or a part of Spain, however some of the Catalonia  
 national football team players are: 

 Sangibarbá and Di Stefano: Argentinians 
 Kubala: Hungarian 
 Neskens and Cruyyf: Dutch 
 Evaristo: Brazilian 
 Sapirissa: Salvadoran 

 And amongst the "Spaniards" we can find: 

 Cesar: born in Leon 
 Luis Suarez: born in La Coruna 
 Pereda: born in Burgos 
 Alcántara: born in the Philipines 
 Velasco: born in Murcia 
 Two of the best Catalonian players of all time played alternatively for and against Catalonia (Samitier and Zamora) 

 If we consider this a national team then we can obviously consider "Zidane and friends" as Marseile National Team. And please don´t waste your time calling me "anti-catalan", please take your victimist agenda somewhereelse
