Pitch invaders can often be looking for nothing more than a hug from their favourite player. Admittedly, interrupting a Champions League match to get your cuddle - as this slightly overzealous Cristiano Ronaldo fan did recently - is a bit much.
But still, at least it's all nice and friendly.
Over in Ukraine, some pitch invaders are not quite as pleasant. Take the idiot who decided to confront Shakhtar Donetsk goalkeeper Anton Kanibolotsky, during their recent 3-2 win at FC Olexandria.
As you can see in the clip above, this "football supporter" thought it would be a good idea to run onto pitch, square up to Kanibolotsky and give him the finger. So what did the Shakhtar keeper do? Run away? Call for help? Beg for mercy?
It's just as well Kanibolotsky can look after himself.
Given the incredible length of time it takes for security to come and grab the guy, he was pretty much on his own…
