As a Nigerian, Apart from our local football league we do support, we still support football clubs at abroad
Most, in fact 99.99 percent of Nigerians support teams in Europe
As I am, the local football league I support is called 3sc also known as "the oluyole warriors" while Arsenal at Europe
I have friend that supports Manchester United, Manchester City, Liverpool FC, Real Madrid but most of my friends I know supports Chelsea FC
Some says they do support Chelsea FC because they believe in Africa, they used to make use of African footballers while some just love Chelsea naturally
It's a matter of choice cos I just love Arsenal FC naturally, not because of anything.
