Rangers chief Charles Green criticises Tannadice ticket plan Charles Green has questioned Dundee United's decision to sell tickets to Rangers fans for February's Scottish Cup tie at Tannadice. The Ibrox chief executive says the club will not take up its allocation and has urged United not to sell tickets to visiting supporters on safety grounds. United confirmed they will sell tickets to any Rangers fan, which Green has condemned. "There are a number of issues, safety has to be paramount," said Green. Rangers announced earlier this month that the club would not take up its allocation of February's tie, although supporters are split over the decision.. The Rangers Supporter's Trust asked fans to boycott the Tannadice tie over United's opposition to Rangers' application to join the Scottish Premier League. Some Ibrox fans have pinpointed Dundee United chairman Stephen Thompson as being one of the most outspoken figures on the subject of relaunched Rangers seeking membership of the top flight in the summer. And Green believes the decision to sell tickets directly to Rangers fans could spark trouble at the match. "We are very conscious of safety, " said Green. We are concerned that Dundee United won't know who they are selling tickets to and how will they know if they're genuine Rangers fans or potential troublemakers? Football needs to be safe and there's no guarantee it will be. The Rangers Assembly is also still angered by Thompson's refusal to refund Rangers fans for tickets when a match at Tannadice in November 2009 was abandoned at half-time because of a waterlogged pitch, which Green points to as one of the reasons behind recent problems between the two clubs. "It wouldn't need a bright guy to tell you that there has been tension between Rangers and Dundee United for a number of years," said Green. We have taken a decision to diffuse that tension but the decision to sell tickets to people who may not be Rangers fans is taking it to a high level. I'm disappointed, I spoke to Stewart Regan (the SFA chief executive) about it the other day when the SFA asked my reasoning. We have been very clear from day one, because of the fans' issues with Dundee United in the past as a board we made the decision not to take tickets and requested they didn't make tickets available to Rangers fans. The reason why is because if we're not selling the tickets then we're not convinced that someone on the outside has that control. It's safety-driven. I would ask United to think again. The majority of Rangers fans said they didn't want to go. There will be a few who do and I can understand that. But I think it's foolish to try and bring in a few Rangers fans who might not be - it could be any number of people who turn up with a red, white and blue scarf on. I can understand that people will want to watch their team play - genuine Rangers fans. There will be people who have not missed a game in years, I recognise that and admire that passion.
