Vini will finally calm down and be on a good conduct. Maybe, the demand for increase in pay might be the problem why he's acting stubborn. He has no option than to humble himself and put in his best for Real Madrid so that, Madrid will give him whatever he asks for. Of course, no player is an Island and all the players in Real Madrid are professionals which gives them less chance to feel too important.
Any player should humble themselves when they're facing a team that pays them and makes them more famous, especially when that team is Real Madrid, which has historically boasted high-quality players, yet they still humble themselves to the team. So, Vinicius certainly shouldn't be arrogant toward Real Madrid, even though he has higher aspirations for Real Madrid, but that's not the way to go if he wants them to fulfill his desires. He must remain calm, especially since he already knows that not all Spaniards like him.
