Aberdeen are investigating social media claims that Rangers fans have bought some of the Pittodrie club’s allocation of Viaplay Cup final tickets.

The club says they shut their ticket office on Wednesday and carried out checks of customer accounts to ensure all those who have purchased a ticket for the match are genuine Dons fans.

It comes after Aberdeen put part of their allocation on general sale earlier this week and enabled people without any loyalty points to buy a ticket for the game at Hampden Park.

Aberdeen say they are continuing to speak to the competition organiser, the Scottish Professional Football League, about their additional ticket allocation and are encouraging fans to contact their ticket office to join the waiting list.

The Premiership club had earlier said they were working to ensure all those who have purchased a ticket for the cup final on 17 December meet what they describe as the “usual stringent rules”.

That came after chief executive Alan Burrows apologised for the way in which tickets had been made available.

Aberdeen were allocated 19,500 tickets, compared to Rangers’ 25,000, and 17,000 of those were sold in a matter of hours and left many fans frustrated.

Initially, those with 200 loyalty points could buy a ticket, with the remainder going on general sale.

Burrows says that – in hindsight – this was an error and those with slightly fewer points should have been given the chance to secure their seat first.

Those with higher loyalty points will be prioritised when the remaining 2,500 tickets become available, the club insists.
