Carlo Ancelotti needs to do some talking to Vinicius Jr about his obstinate actions towards others. He's recalcitrant to authorities and that's no good on his reputation as top player. Real Madrid main player is the Brazilian. He's always delivering the team when all hope is lost. Vinicius Jr have been absolutely the best player in the team, taking everything on his shoulders and winning titles with the club. So some respect should be put on his name. Vinicius Jr is a player that's fierce and aggressive towards oppositions. He easily get perturbed following the annoying behaviors of his opponents and we know Vini, he doesn't know how to withdraw from these scenes when they come up. He's given 4 match ban and Real Madrid making appeal already because he's important for upcoming matches.
If we look at what happened, this is actually not the first time Vini has been seen emotional on the field because he does seem to have a slightly bad temper when in a match with high tension which of course must be minimized immediately so that he is seen better as a professional player.
Now the 4 match ban could even be more even though Madrid also wants to appeal but I think this is not to defend Vini but to make Vini more aware that what he did was detrimental to the club and without reducing respect for Vini I think as long as his temperament is bad like this he could not last long as a star player.
