When I first started training, I learned the lesson of "garbage time"and since then I only play 9 players in a match if I am doing single position training. Trainee playing 48 minutes, the other 4 positions covered by a starter and a backup. This has always worked in ensuring my player got exactly 48 minutes unless injured.
In my latest league game however, my trainee was substituted off twice, and lost 2 minutes. Luckily as an 18 year old, this will not affect this weeks training, but I am confused as to why this happened. There was not even a garbage time note in the game.
The game is linked below, and here are the time references for when my trainee (Zhidkikh ) with no backup and no reserve was subbed off:
