It seems like soccer cheerleaders are leaving these days..

It seems like most cheerleaders, including those from FC Seoul, are leaving soccer cheering behind. Why is that?
Soccer is a sport where there are no cheerleaders or even cheer captains at all.
No matter how much I try to look at it positively, it feels like soccer is a sport that doesn't need cheer captains or cheerleaders..
Why do only the spectators cheer in soccer? At most, there are just call leaders..
