I think we're now into standard Everton mode.
What we have done is the new regime way of thinking "lets just smash the really important stuff first".
Now we're into the normal, Everton "let's see what comes up for a reasonable price" mode. We have places to fill but "will go with what we have" or wait for an injury to come back so it can be "like a new signing".
The only abberation for that, to me, is Lukaku. It wasn't a certainty he would leave when we ligned up Pickford/Keane/Klaassen, Sandro & Rooney and if he is in our team now? Well, we're all much more optimistic aren't we.
So a replacement for him is the only outlier to my theory and we get to see whether the new regime is good at reacting to stuff as well as they proved they can plan for stuff this summer.
