I think people are making too much of the youth in a negative or positive way.
LVG took a calculated risk in having a squad with only a certain amount of experienced players. He could have had a squad full of experienced players, but those that would replace the youth in the current squad would be real bit part players. Debatable whether they would make much of a difference as most of them would not make the first team in the normal course of events. The fact we have so many injuries, he would have had to use those players as he has done with the youth, so what is with the LVG is forced to use them as though it is some big negative, seems such a weak point to attack him on.
It also seems strange that the LVG Out brigade have been arguing mainly on 2 fronts, the football has been dross for a large amount of LVG's reign (not many going to argue with that), and they have no confidence that he will win anything. The latter being the main argument for having Jose. So it seems strange that if LVG gets the team in a position to win something, you still want him out. Particularly because to get to a position of winning, the team will have to start playing consistently at a high level.
Why not just forget the weak arguments (and the "that doesn't count because they are shit" arguments to make a petty point) and stick to the plain old "I want him gone". You don't have to justify that point anymore, because there are so many holes in your arguments.
