Training Guide for every player.!!

1) My team needs,let's say, 4 training sessions to prepare my next official match:
should I launch the training sessions 4 times for each role (GK,DC,....) ?

Otherwise 4 training sessions would not be enough to train all roles.

You need 4 any training sessions. Take a guy from the bench and do a session with him 4 times. Voila!
No need to train every position 4 times.
