I never said just keeping possession doesn't equal creativity by default, but possession teams do tend to create more chances than teams who rely on moments by individuals. I think you missed the part where I said we have created 16 big chances this season, and only two of those come from Bruno. That is the third most big chances in the league of all the teams.
We are not struggling creatively without Bruno, we are struggling with finishing, balance and giving away possession easily so we spend a huge part of the game trying to win the ball back. Why would we not try to fix that when the creativity is in place? Mount could be a better solution for that aim. Having a better balance in the team when we are creating a bunch of chances will likely make us even more creative, because we would have the ball more. This isn't LvG's team.
Wirtz is a better passer than Bruno, but that's not what we were discussing. We were talking about creativity and Wirtz doesn't create half the amount of Bruno's chances. Same applies for Musiala, he is undoubtedly a much better ball carrier, but you were arguing for creativity in the team. By using these arguments for these players, you are kind of proving my point that you don't need to be as creative as long as you can offer other qualities. Mount is also a better ball carrier than Bruno and is excellent at receiving on the half turn that can potentially open up a lot of space.
He is an issue because of his general performances, not because the players aren't finishing chances. And it is not like the chances came from him either, so if he can't do what his biggest strength is, what is the point of playing him? It has to be said, that he is also at fault for poor finishing, as we could see against Fulham and Palace with the outside of his foot. He has regressed hard in terms of finishing, and he doesn't score enough goals for a number 10.
