UEFA's executive committee on Sunday warned the FA and the Russian Football Union "it will not hesitate to impose additional sanctions...including the potential disqualification of their respective teams'' should fan disorder continue.

But while Dyke condemned the trouble involving England supporters in the streets of Marseille, he insists video evidence proves Russian fans were to blame for the ugly scenes inside the Stade Velodrome, a claim he feels is backed up by UEFA's decision to only instigate sanctions against Russia.

Dyke wrote: "Whilst we absolutely share the executive committee's concern regarding these abhorrent scenes, particularly in the Stade Velodrome on Saturday night, I would like to make some serious points.

"The implication in your jointly-addressed letter is that English fans were in part responsible for the terrible incidents at the end of the match with Russia. This is contradicted both by the video evidence and by the fact your independent disciplinary bodies have only instigated sanctions against the Russian Football Union.

"We believe the stewarding arrangements in place were unacceptable. Supporters were able to get in with fireworks and flares, and then let them off, and there was insufficient segregation between the Russian and English fans, particularly given the events of the previous two days.

"Having said that let me be clear, we join you in condemning the horrible scenes in Marseille away from the stadium on Thursday, Friday and matchday."

England manager Roy Hodgson and captain Wayne Rooney released a video on Monday in which they urged England fans to stay out of trouble.

But Dyke has called for security to be improved in the build-up to Thursday's match with Wales in Lens - particularly as Russia play Slovakia in nearby Lille on Wednesday.

"We are planning to use our high-profile individuals to ask English fans to act responsibly and in a respectful manner and we take seriously your suggestion of sanctions," added Dyke.

"We understand there is to be an alcohol ban across the host cities and we would welcome this, particularly in Lille on Wednesday where many English fans have been asked to gather ahead of Thursday's match against Wales in Lens.

"We have, following consultation with the authorities, advised our supporters without tickets for the match in Lens to congregate there, and whilst we will be working hard to positively influence their behaviour we have serious concerns around the security arrangements for the city in the next few days.

"These concerns are heightened with the knowledge that Russia will play in Lille on Wednesday afternoon."

Six England fans have been jailed for taking part in the violence that spread across Marseille, with all banned from France for two years.

The men, who all appeared at court in the city during a five-hour session on Monday, were imprisoned for between one and three months.
