Vinicius is doing Vinicius thing.
Although he played well and consistent, but he always can't control his mouth to talk shit in front of opponent's fans.
It's a good idea how Xabi to put Vinicius on bench, he always play as a starter because no one can replace him. But, now Xabi don't mind to bench star player and let the young player to play.
Vinicius is doing well because he is a great player but he's a human and may not be liked by everyone.
Vinicius has been consistent right from his early days in the team and he can't keep calm when he's been constantly abused and bullied by fans of the opponents he shouldn't be calm.
Xabi Alonso didn't make Vinicius to start from the bench because he is not good he just wanted to try a different performance and to use him as a super sub not that he wants the player to know that he can be benched let's not get things wrong.
