trapQ:
So you feel communication would be effective when some of the players are not Yoruba and don't hear the language.
For reference, a non-yoruba player was with the ball and the coach was "supposedly" giving instructions in yoruba. How did he expect the player to understand what was being said?

don't get your pants tied in a bunch....so only Yoruba people understand Yoruba? bros, reflect slowly and calmly...
