Kevin-Prince Boateng has said he is upset that Schalke chairman Clemens Tonnies did not receive a more severe punishment for recent racist comments.
Tonnies decided to step down for three months after finding himself in trouble over recent comments about Africa.

The comments caused an immediate outcry and Tonnies quickly issued an apology.
