The inaugural Festival Cup, featuring Hibernian and Hearts, does not appear to have captured the Edinburgh public's imagination - with ticket sales for the Easter Road match proving slow.
Edinburgh wants to establish a football tournament at festival time
Hearts have been allocated 3,500 seats in the South Stand for the 2 August match, but have only managed some 700 sales.
The match kicks off just seven days before the start of the new season and is being staged to coincide with the capital's International Festival and Fringe.
However, Hibs and Hearts are scheduled to meet on league duty at Easter Road on the second weekend of the SPL campaign and this may have put fans off.
"Ticket sales may have been very slow but the fans are obviously thinking about the SPL derby at Easter Road just two weeks after the friendly," Hearts Communications Executive Nadine Urquhart told the Edinburgh Evening News.
Event organisers hope to tempt big-name sides from Europe to compete in future Festival Cups, with Edinburgh hoping to cash-in on its twin-city links with the likes of Barcelona and Munich.
"We appreciate there is a league game between the sides just two weeks after the Festival Cup but we would urge fans to rally round and support the event and ensure it is a success in years to come," said Hibs spokesman David Forsyth.
