Bayern Munich coach Thomas Tuchel admits stopping Vini Jr will be key to defeating Real Madrid.
Bayern are in Madrid for the second-leg of their Champions League semifinal with the score locked at 2-2.
Tuchel said: "It is difficult to think of how to stop Vinicius, many have tried and have not succeeded. I can say that we can stop all the passes, but it is not possible. Kroos and Valverde can make 70-metre passes, Vini receive, start dribbling and that's it, we have to admit it.
"We are going to try, but we know that it can hurt any team in the world and that it is possible that not everything will go perfectly tomorrow. But we still have the right mentality to beat Madrid with Vinicius and get there to Wembley.
"The key will be to set the pace of the game. I don't think there is one team that dominates all the time, there are going to be phases. We need to have the ball to recover and look for deep passes, but we have to be prepared for their transitions. Theory is one thing and applying it in the field is another.
"The game belongs to the players and we must try to make them as good as possible. The eleven and the changes will be important. You have to have faith because they play at home and perhaps play more offensively than away.
"We know we have a tie and whoever wins goes to Wembley, that's it."
