Kevin-Prince Boateng called on Wednesday for football teams be forced to forfeit matches when their fans racially abuse players, after Mike Maignan was targeted by Udinese supporters at the weekend.

Former Barcelona player Kevin-Prince Boateng said that he was made to say that Lionel Messi was the best player in the world despite personally believing Cristiano Ronaldo was the better player.

The tale of the Boateng brothers Jerome, George and Kevin-Prince -- two of whom made history by facing each other at a World Cup finals -- has hit the stage in Berlin.
