That's not what I meant at all. You're telling him not to write nonsense about Bayern. He's free to say what he wants about Bayern, especially since this is a Juventus, and not a Bayern, forum. Of course, you're entitled to respond as you deem fit. We don't have more say as Juventus fans, but by virtue of the law of majority, you're more likely to get hounded and harassed if you're not a Juve fan, and deploy a certain "holier than thou" attitude. I think I was only stating the obvious.
You're free to desire a German coach for Bayern, and it makes perfect sense. However, I got the impression that you're undervaluing the effort and work of Allegri. I wouldn't want Mourinho either, so we're thinking along the same lines with respect to that particular point.
