Why don't we start with vdB instead of Bruno? I'm sure he will make safer passes and not lose ball posession as much...
You can't ask Bruno to be perfect. To keep his great output of attacking chances, assists and goals but be more conservative with his passes.
I remember how before him, our forwards only wanted balls passed to their feet. And most of those times, they would end up passing back or to the sides. Now they'll run to the empty space, because they know Bruno will try to pass those through balls.
Also, the way the teams plays, presses and the other midfielders position themselves, influences Bruno's play. Maybe if we didn't leave that huge gap in the center midfield, we wouldn't feel the need for Bruno to play deeper on the midfield and he wouldn't be more exposed when making more difficult/risky passes. That puts him further away from where he shines. But if the coach can't change tactics, then I guess he should make Bruno play as a CM and not as an AM.
Anyway, if we played better as a team, Bruno wouldn't feel the need to take more risks to make something happen.
Certainly Bruno can improve a few things, like be a little bit more patient sometimes. But there's a lot more and more important things that we have to do better. Even if he started to be a lot more conservative with his passes, we would stil have big problems to solve but without all those goals, assists and goal chances created by him. A lot of things must change, before changing anything on Bruno's play.
