Sulley Muntari walked off the pitch in protest after claiming he was being racially abused during Pescara's defeat at Cagliari on Sunday.

The former Portsmouth midfielder and Ghana international, who also played for both Milan clubs, complained to the referee about the abuse but was booked for dissent.

Muntari left the field in protest leaving relegated Pescara to play out the final few minutes of the 1-0 loss with 10 men.
