I totally agree with cookizzz, having a stable first team helps alot as opposed to switching players around every match. I also try and stick to 1 formation but if a manager tries to counter it then I switch my formation but at the same time, try and use my first team. It is a bit difficult to stick to 1 team and 1 formation due to injuries and suspensions. When it comes to using the assistant, I tell him to take a seat, I should charge him for a ticket!
