Confirming the encouraging sales figures, Ticket office manager John Ford told the club website: "Roy Keane coming in as manager has certainly seen a boost in season ticket sales and we are now over the 15,500 mark.
"We have had a six per cent increase in Early Bird season ticket sales compared to last year and we have already sold 150 or so more tickets this year than we finished with last season.
"We're still getting a steady flow of supporters purchasing tickets for next year as well and there certainly seems to be a buzz of excitement amongst the fans."
