Ghanaian Midfielder, Sulley Muntari, 32 after complaining to the referee about the chants was punished rather for dissent, prompting him to take action himself by leaving.
The midfielder appealed to the referee to stop the game, claiming the home support were racially abusing him with chants
But referee Daniele Minelli apparently did not hear the chants and instead opted to book the former Inter player for dissent.
Muntari then walked off the field, leaving the already relegated Pescara to finish the game with 10 men which they lost 0-1 to Cagliari
Pescara coach Zdenek Zeman criticised the decision to punish the 32-year-old instead of dealing with the alleged abuse.
“Muntari asked the referee to intervene, but he did not do it,” he told reporters. “We talk so much about racism, but then we just move on. This happened to Muntari who has played in Italy for several years – we want to change the mentality.
“He left the field because of the chants, but we should not have to take justice into our own hands.”
