Celta de Vigo is a professional football club from which country?

Tony, People called the Celts lived in the British Isles (ie Brythonic...), France (Gaul), Switzerland (Helvetia), Bulgaria, Spain, Northern Italy (cis-alpine Gauls).... The term is used loosely. They have some common characteristics but I don't like the term. The Greeks, Romans then and european archaeologist use it as catch-all for Indo-Europeans in the area. They had some common language elements, and traded. And some common ancestry. But not one people.

I know that Moors lived in Spain but never heard of Celts living there. They were in Ireland and I thought exclusively in the area of Great Britain.

The word "De" gives away the fact that it is a word in Iberian language (Spanish and Portuguese or more like Valencian). Therefore, you should use double chance and click Spain and Portugal 😒. If you do not know Iberian language, then at least know words like "de" or "hola"
