They could say for unintentional handballs or handballs which are not DGSO that it is an indirect free kick in the box. Less punishing but still a handball

I think FCK have a perhaps healthier setup than most premier league clubs, financially. The same level of player that FCK have in the Prem would likely cost much more. Regardless of how they would do in their first season, they would never be able to financially compete with and EPL club, and likely many Championship clubs.

In their first season in the Prem, I can see them scraping into as high as 16th, maybe, but that would only be in a season like this one where the bottom 4 or so are really not performing well.
