Maragall, thinks that there shouldn't be any problems to admit Catalonia as it was in this country where the roller hockey was invented and legalised as a competitive sport. Often when quesioning why Wales, Scotland and Northern Ireland are full members of the FIFA and therefore can compete against England, the answer has been that football as a competitive sport was invented in the United Kingdom.
It seems to me that this is a very valid argument in defence of the Catalan recognintion!
Maragall has also stated that in the last world cup in Macau, China was represented by 3 different national teams (Macau, Chinese Taipei, China).
