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.
Neymar is just too young too realize that he is not the center of everything. He is still young and talented that what makes him arrogant. Cavani has been taking penalty kick since before he arrived therefore he should realize his position. Perhaps he wants to score more goals to compete with messi and ronaldo in ballon d'or, well he wont have chance though
