That's a weird take on the situation.
Whatever the forest fan did to end up on the floor is a separate issue, but for a professional football player to approach the scene and start stamping on him several times, as the video revealed, is shocking and out-of-order. So it is not 'boohoo' (which is what I think you meant) but instead a pattern of violent and aggressive behaviour by a really nasty piece of work. Sheffield United will use this opportunity to get rid of him.
