At first glance the figures do appear a little worrying but it's very difficult trying to draw comparisons between the 2014 calendar year and the first six months of 2015 and any conclusions could be way off the mark. For example, 2014 includes the play-offs and Wembley, the figures to June 2015 include two months in the close season when income would be at the lowest. When are season ticket sales for 2015/16 recorded? Presumably after June 2015. 'Other receipts' I assume are tv revenues but again how and when are these distributed?
Overall, we'd like to see percentage increases instead of decreases but there are too many uncertainties to suggest we're in any financial difficulties (but the huge player turnover won't have helped).
