Let's forget about football here and face the reality about politics, this is a game on itself that is common in every settings, men play politics as an act to dubiously manipulate result from what its meant to be to suit their selfish desires and taste and one of the ways through which politics is being displayed is through racism, why do you think racism occur, it's just a simplify way of perverting justice in favour of one over the other using color or ethnic groups.
In general, however, football is football, and politics is politics. These two things should never be blended. Football is a king sport that represents unity, teamwork, and human emotions. Politics is a complex social issue that influences people's perceptions. Allow personal feelings and thoughts to influence a collective, international image.
