UEFA have 'no specific worries' about the all-English Champions League final between Manchester United and Chelsea in Moscow on May 21.
United and Chelsea chief executives David Gill and Peter Kenyon were due to meet UEFA officials in Moscow on Thursday to discuss preparations for the final.
Each club has an allocation of 21,000 tickets with the capacity at the Luzhniki Stadium being set at 69,500 for the final.
UEFA director of communications William Gaillard told Sky Sports: 'We have no specific worries or problems.
'I think both clubs have developed a tradition of travelling abroad and both clubs are very well organised.
'We have never had any problems with either of those clubs' fans. We are looking forward to welcoming them in Moscow and sure they will put on a great show.'
United and Chelsea fans who cannot get a final ticket as part of their clubs' allocation may buy tickets from other sources but Gaillard warned: 'I would very much discourage them. There is no guarantee that the ticket they get is a bona fide ticket. Also every ticket has a number and every number identifies a person.'
