I've always started new seasons, and every season I don't succeed to get almost more than half in tactics acknowledge... Even if I train tactics before the friendly matches !
Make sure you have a coach with good tactical coaching and is set to teach tactics, increase the duration of the match preparation and always set it to tactics, also change the normal tactics to team cohesion and increase the intensity to a High level. Do all of that at the start of the preseason and continue with it until December-February and the outcome will be good

Good luck!
