Burnley and Leicester make sense but what’s the basis for the Leeds claim?

Everton should counter-sue Leeds, Southampton and Nottingham Forest for ‘extreme taking of the piss’ if they try to get money off them for this. Forest are obviously still in the Premier League, and Leeds and Southampton would still have been relegated if Everton had a points deduction too. What are they going to sue for, the £2m more they would have received in prize money for finishing 18th and 19th instead of 19th and 20th?
