I think it is a move in a wrong direction for the FA to deduct 10 points from Everton at this point in time when the club is facing relegation battles, this will only dampen their confidence and also jeopardize everything they have worked for so far. Everton still has the right to an appeal though but if they lose the appeal then it would be very disastrous for them and may cost them their chances of escaping relegation so let's hope that everything goes in Everton's favour when the hearing for their appeal comes up.
Previously, Everton had received a 10 point deduction and fell into the relegation zone, but slowly they were able to get up and get out of the relegation zone like they are now, so If the FA does the same thing for the second time, I'm not sure if Everton can get back up, now Everton has been accused of violating financial rules regarding the club loss threshold, despite the club now an appeal has been submitted but it seems very difficult to fight against the federation, so I think is very likely that the charges will make Everton relegated, apart from Everton, it turns out that Nottingham Forest also suffers the same fate as Everton, namely being threatened getting points deductions, so far I think the FA looks unfair when they seem to continue to investigate medium teams without wanting to try to do the same for Chelsea and Manchester City who are also rumored to have committed financial violations all this time.
