People don not think that way just that what I sent people are doing most is speculations because kompany doesn't have a very sound track record up on which one can consider as really reliable. It's something that only a few will take exception off and you cannot hold them to that as their reasons looks very reasonable. One thing I believe is that sometimes responsibilities and expectations can make someone get better than they have been before all of that came up on them, so I wouldn't be amongst those who wouldn't make room for consideration as to what kompany can be capable of.
I think you are right that people are mostly guessing about Kompany future because he has not done great job in past. Some people still believe in the Kompany but it is reasonable to have doubts. I also think that when anyone is given more responsibility they can rise to challenge and do better than before. So I think it is fair to keep an open mind and consider that Kompany might surprise us and do a good job. By doing this we can balance our doubts with willingness to give them chance to show what they can do.
