We took a while last season to get going and for Koeman to get his message across. The first four or five games last season masked that we weren't really playing that well. This season we've made wholesale changes to the squad and it's pretty clear for one reason or another we're having a similar start to last year, made harder by several new players, not just new to Everton but new to the league who are going to take time to adapt. Some might never adapt, I've never liked big overhauls of a squad and the chances of everyone that was signed making an impression are probably quite small.
It's going to take time, certainly more than 4 league games and a couple of Europa ties one of which became part of pre season. Calling for him to be replaced already is fucking stupid.
