To shape a habit, you need to repeat it. It will take time, but eventually you will be able to do it almost blindly. The Manchester City players did not even have to stop to see where their teammates were on the pitch, because they practice playing this way every single training session. I'm not saying we should play like City, but to change habits and be confident in it, you have to be exposed to this regularly. This is what I think is clear that Everton is missing, and which is mentioned when people here call for an identity, style of play, structure, etc.
