Several of these managers aren't attending those 50 friendlies. The team is on auto-pilot playing with 0% condition.
All manager really has to do is login every 2-3 hours and heal players.
I feel sorry for new players who don't have lots of health packs, lack fully upgraded facilities to prevent injuries and are too a low a level to beat up on others in friendlies.
Creating a new account just became much less appealing.
