What you actually showed was that Bournemouth make 4 million when in the champions compared to 27 million Newcastle in the premier league
You'll find the gap is not as big now and all Bournemouth would need to do to dramatically shorten the gap is build a new stadium of say 30k capacity and it would fill up with premier league fans and corporate seats getting sold for canny wedge.
Look at West ham man, 27k stadium at the time and the same as Newcastle who have a 52k stadium sold out nearly every week, prawn eating wankers and foreign fans have completely ruined the English league. The premier league is a huge competition eating monster like a Starbucks on every corner.
