I find Everton fun to play with, but they pretty much have no weaknesses and nowhere they need to improve... so I get bored easily, and it doesnt feel like MY team.
You should consider playing 3 CBs ands no fullbacks... I often do that with Everton. You have lots of wide midfielders, so width isnt an issue, and the fullbacks you have arent great or can play elsewhere. Play with a DM or AMC instead.
