fm 2020 training schedule - need help / newbie

Will I find somewhere ready training schemes to use in FM 2020? I found a package but it had over 40 patterns - I can't understand it

or question on the other hand. Will leaving trainings for any coach ok? What attributes must a high trainer have to manage it well?

Leaving training to your coaches is fine, the main attributes they need to have are determination and motivating as well as whatever type of coach they are attacking/defending/technical.
