Watching Luton vs Huddersfield right now it amazes me that Luton still play at Kenilworth rd. I used to love their orange kits back in the day. The max capacity of their stadium is smaller than Bournemouth's!
Sunderland and Newcastle are weird clubs. Attract huge support but in a depressed area of the country so the big stars don't want to live there cos it's so grim. Also, dysfunctional ownership doesn't help.
Unfortunately, this is the way most of the European leagues are going. At least in England there are half a dozen that have a shot. (Leicester being an outlier).
