Question about training. at beginning of season1. Only played 2 friendlies so far ;)

So i hear that if you ask your coaches to do alot. they can get annoyed/ tired?

I have also heard that some people only enable certain coaching attributes that the coach are good in so that they can concentrate only on that.

What im wondering is what is the best way. To only let your coach train people in what he is really good in. Could the squad learn more if say a few coaches were teaching them different stuff or Is it quite effective to have a coach with strong ... attribute enabled only having him train the squad.

Found it bit difficult phrasing exactly what i mean but basically i guess. Can anyone tell me what is the best method to training the Man team 1st/res/u18's in the game. Would truly appreciate this. Thank you for reading. Will look forward to the replies on this. Byyyeeee
