i think that 1 or 2 practice games every week will be the best move.practice between our players,without anyone can see the outcome,except us ofcourse.every manager will can try new tactics or players in other potitions etc.that means that everyone will learn their own team better,without anyone else know.if i try a diferrent tactic in my friendly game,anyone can see that.but in a training game,only me knows what happens.
