it is interesting that people are talking about the dispute between Neymar and Cavani regarding taking the penalties and free kicks, I am sure that story is very much focused on the performance of the team. though Neymar is the key player in this squad so that he should take the penalty kick but Cavani is also very succeeded in terms of the spot kick. so coach should discuss and should take a solution to resolve this problem. Otherwise, this problem will get problematic an issue in the squad.
