This is just bizarre. It's a portrayal of a fictional, comic, primitive tribe. How is that offensive to black people such as Reina's team-mates?
You wouldn't expect a white footballer to take offense at the comic portrayal of a white motorcyclist as a violent musclebound psycho in one of the other ads, so why would you expect a black footballer to take offense at the comic portrayal of a black tribesman? The implication is that all black people are the same, so any negative portrayal of a black person must offend all black people - but how racist is that?
Madness.
