Is a "big deal" being made of it? Isn't the nature of a forum to discuss things and isn't naming six players beyond the norm and worthy of discussion. (For many, including me, it's inexcusable to a club peddling the notion they have this great youth set up).
The reality is that almost any criticism of guardiola is met with huge opposition regardless of what it is. He's had some pretty low class moments this season , regardless of how well he has done, and people are allowed to comment on it.
On the other hand if you're saying that they don't have a single young player good enough to even sit on the bench, the a whole new criticism needs to be discussed.
