I’m not sure if this is a serious question or not..?
If yes, you’ll need to understand that 90% of real world football tactics do not work in this game. As it’s a simulated management game there’s proven tactics that work and I’d be trying to stick to some of these if possible.
Check out teams doing well of a similar standard or a little higher and see what tactics they use and try to copy a few. You can do a bit of experimenting and see which word for you.
