Does any know how this win will be received in the Catalan & Basque regions of Spain?

Are they fully behind the national team or just interested in the success of their own players??

I can’t imagine any other country that would encounter this kind of problem,
The only loose example I could conjure up would be if the United Kingdom was forced to enter one team.
How would a Scotsman cheer on a team with at least 9 English player??
