Everton's performance during this season was well enough but didn't you know Everton's owners are not in a good situation and this team is not in a good situation. There is even a chance for Everton to get relegated in this season because of that. I think if they really care about Everton, they should find a new owner and chairman for this team before it gets too late.
Everton can still save themselves from relegation this season, especially when I saw that Everton was able to win at home to Burnley yesterday which has kept Everton safe from the relegation zone for a while. However, if Everton still wants to continue their current performance, there are several things that need to be considered for the good of their own team. And one of them is what you said because I think Everton is a pretty good team even though they don't often get good results in the Premier League.
