I`ve been abroad following England a good few times over many years and to be fair there is an element within the England support that can be troublesome, but from what I`ve seen it is usually a very small element within the overall support. I have witnessed, likely due to the alleged "reputation" of the England fans, the locals and / or opposing fans coming out and looking for trouble. Usually the police in the particular country we are playing ally themselves on the side of the locals or opposing fans, whatever the situation, and before you can say "England fans causing trouble again" we are a news item.
Most England fans who travel are responsible, dedicated, intelligent people who passionately support the team, enjoy the country they are in and welcome the rapport with the opposition fans and the local people, unfortunately this scenario is often spoiled by the likes of the half wits, as we`ve seen in the last couple of days, in this case from Marseille / Russia / God knows where, who seem determined to set themselves up against the English hard men.
