I doubt it will be much more than 1.5K. It's hard to get to; it's expensive (the Dubrovnik route has been closed due to the Tans visiting Croatia, and the Bari option is more aggro than it's worth) with plane tickets now nearly €400; it's midweek; it's the start of the campaign rather than a make or break game or a playoff; and as far as I know there isn't anyone on the Montenegro side who plays for either Liverpool or Manchester (correct me iof I'm wrong on the last one). Judging this with our midweek visits to Romania in 1997, or to Belgrade in 1998, this is not a game I would have thought many fans fancy.
