Bringing personal problems to the field is an action that will damage teamwork, so I don't think Vinicius has a revenge mission as discussed. Because the news was exaggerated by his fans, Rodri is still injured so there is no reason to prove themselves to each other. Let the past pass, now Vinicius only needs to focus on winning against Man City and being able to play solidly.
It will be a very bad one to not have control over your emotions enough to want to bring grievances to the pitch such that it gets to affect the performance of the players and the general chemistry of team members thereby affecting their total rhythm within team members while in the field of action, but I feel at some point the case is such with the team in the case of Vinicius it's just some exaggerations from fans maybe.
Why would Vinicius take revenge on the field? It would only harm his own team because he prioritizes his own ego. If he is too emotional, it will only harm him because he will definitely play too hard so that he cannot be compact on the field. He must have forgotten it and in the competition in the play-off round, each player should prepare themselves to do their best because teamwork is very important in this case.
