Perhaps due to the accustics or something he thought that was where the chearing was coming from. Perhaps he has watched to many American sports games. I dont know either. But as frustrated as Pro might be the idea that he would do that on the field to the coach is crazy. His agent could be complaigning publicaly or he could be demanding a transfer etc. I cant think of anyone who has ever disrespected a coach on the field in front of a crowd,,,,, Well mabey Tavez or Balotelli but they are proper assholes and Pro has always seemed pretty professional on the pitch.
