Whenever your training minute allocations for the week get messed up to the point of it not being worth trying for 48 minutes each per trainee. This usually happens to me 3 or so times a season due to injuries, stupid coaches or forgetting to set line-ups.
Also, when you have multiple important games in a week preventing you from giving young trainees enough miniutes.
That's usually enough FT and stamina for me and I end up just training 1on1 or RB for 2 positions instead of 1 postion training in the short weeks.
how can I get my team to stop giving away passes just after they've stolen one!
Try a slower paced tactic?
