I edited it to say 75% for Nigeria.
Have to say I'm highly sceptical of being able to gain Belgian citizenship in just 3 years, when my wife and I looked at places she could easily settle and get EU citizenship it was generally at least 5 and I don't think Belgium was an exception. As @Lxxx says though, if he tears it up again then special dispensation might come into play.
I seem to remember that Wenger used to have this dodgy plan of strip-mining Ivorian talent where he'd operate academies in Abidjan, bring the most promising youngsters over to Belgium (Beveren, specifically), park them there for 3 seasons to get them a European passport, and then take them to Arsenal or flog them, or just leave them to fend for themselves if they turned out to be not good enough.
Eboue was probably the only one who made it to Arsenal through this route and then they were rumbled, but it was definitely a viable plan at the time.
