Sometimes football teams hold open training sessions to give their fans a glimpse of their heroes. They usually do this under the assumption that the fans will be respectful and wait til the end to try to get photos or autographs. You shouldn't make that assumption if you are Galatasaray.

I like how the security guard makes up for letting the fan on the pitch by giving him a kicking.
