Precisely my feelings
I try to compare with some portuguese medalists that were born in other countries (Obikwelu, silver in 2004 100m, born in Nigeria but living in Portugal since 1994; or Nelson Evora, gold in 2008 triple jump, from cape verde, but in Portugal since he was 5), who you can see they really are proud on representing Portugal, and they are inspiration to people here.
So I think: "if those guys were only 'tranfered' to Portuguese team, would I be proud? What would be the feeling of going out there and saying 'hell yeah, we did it! Portugal!!!' ?"
