I take it you don't know how to use Photoshop?
I don't think this is a Photoshop BTW. I think it's just a kid in the stands and I don't know why anyone thinks it's a ghost. Is it because his clothes look a bit old-fashioned? Maybe his parents are the kind of parents who insist on dressing their kids oddly like making them wear something formal to a soccer match. Or maybe the detail is too low to tell exactly what he's wearing.
Seriously, why is this considered a ghost by anyone?
