The Champions League is one of the most-watched tournaments in the world big teams, like real: Madrid, Barcelona, and Liverpool play.
An incident just happened a ref called a player ¨black¨ and he got very offended by it. Both teams then stopped the game until they got a new official to ref the game. They did not want him.
