But is any of those married to a citizen of an EU country? Marriage can make some paperwork faster and easier (working visas, citizenships...).
Doesn't matter the European citizenship, it is about the country citizenship (you aren't gonna be Spanish because you have Italian wife) , according to wikipedia you can get Citizenship in year if your wife is Spanish.
Anyway, I think Suarez will get it before next season, and for January we have one spot.
They can apply after two years, but then it can also take up to two years because the Spanish State is still living in the dark ages.
People I know who got UK,US,Canadian citizenship took two years after the needed time to get their passport, IIRC my cousins who got passport from Norway and Romania needed additional years too,but not 100% sure. It is universal tbf
