ST Johnstone's tremendous response to season ticket sales following their immediate return to the Premiership may reduce the number of tickets available to visiting Celtic fans. The Perth club has already sold more than 2,000 season tickets, putting them well over halfway towards their stated target of 3,800. This surge in sales could lead to Celtic fans receiving only two stands rather than three for league matches at McDiarmid Park. Earlier this summer, St Johnstone revealed plans to allocate three stands to Celtic supporters, sparking a backlash from home supporters. The club promised to review the situation based on season ticket uptake, and with sales surpassing the 2,000 mark, that target now looks increasingly realistic. Celtic fans will be keeping a close eye on season ticket sales in Perth over the coming weeks. The stronger St Johnstone's numbers become, the more likely it is that away allocations will be reduced when Martin O'Neill's side makes the trip north next season. St Johnstone's season ticket sales have been driven by the club's momentum following their Championship title win. The club stormed to the title at the first attempt after relegation and has carried that momentum into the summer. Supporters have clearly bought into the project, with the club announcing the impressive season ticket sales figures. The impact of these sales on away ticket allocations will be closely watched by Celtic fans. As the season approaches, St Johnstone's season ticket sales will continue to be a key factor in determining the number of tickets available to visiting fans.
