The head of Moscow's sports and tourism department Nikolay Gulyaev told 'Sportsmail' that 'security is our top priority and top concern', also responding to whether England fans will be allowed to celebrate in numbers by saying: 'I think you have to direct your question to the police'.
Organisers in Moscow are determined to clamp down on congregating in bars in order to avoid clashes like those in last summer's European Championships in France.
Threat of imprisonment to any Russian fans who cause trouble, as well as the decision to not give a visa clearance to travelling fans not in possession of a ticket, are some of the measures to be taken by the tournament organisers.
