VIDEO: Russian hooligan filmed terrifying Marseilles violence on his GoPro
So choreographed were the attacks from Russian hooligans that they filmed their exploits on GoPro cameras.
Roy Hodgson and Wayne Rooney recorded a video message for supporters, calling for them to act responsibly and respectfully and avoid incident in the coming days.
Russian and English fans are again due to be in close proximity, having been scheduled to play just 23 miles apart in Lille and Lens on consecutive days.
A sizeable Welsh contingent will also be on hand, bring the 'derby' atmosphere into the equation too.
It may be difficult for fans to avoid fans if they are singled out by thugs like the gentleman wearing the GoPro in the clip below.
There are no graphic images but the lack of regard for the welfare of others is terrifying.
