As a leeds fan, I think I have 4 takes on this.
1 - The 10 pts mean very little this year. There are 3 terrible teams in the league, you'll stay up with 30 points probably. Can't see the penalty resulting in relegation.
2 - You broke FFP. You did so knowingly and then tried to cover it up with dodgy accounting. The penalty is fair enough - You got caught and lied about it. Suck it up.
3 - Your big problem isnt the 10 pts, its Burnley and Leicester. Leeds, Southampton etc.....have very small claims, which amount to a couple of million for being 'cheated' out of a place in the league, but neither resulted in a substantial impact. Burnley and Leicester however..........You could easily be looking at a couple of hundred million compensation and all the fun and games that come with that.
4 - This is for the 21-22 season. Your still not compliant with FFP today, so need to fix that pronto or you'll be proper hammered. As a result, there is an urgent need to sell players and reduce the wage bill - and forget about strengthening. I think this (and the 3rd point) are your main issues. The 10 pts won't mean a whole lot and is short term - a big compensation bill and a wage bill that is hugely out of kilter with your revenue are longer term problems that could bury you for a good long time.
