Helping fellow fans - as well as opponents - was found to be of importance to some of the most dedicated football supporters, which may challenge stereotypes about hooliganism.
A new study found diehard fans were the most violent, however the research also revealed the very same fans were the most likely to show kindness.
The closer a fan was to their club, the more likely they were to be violent. It was also found that men were more likely than women to have been hostile towards rivals.
