First must fix some old bugs (like the subs or the penalties in asso games)
Then reduce the troll or fixed games.
Give an advantage for managers who are watching the games. Make for example the bonus active and not cosmetic and the game play must respond to the orders we have set or change. Formations and tactics should be to the great degree.
Must change the training system with a different development of skills and quality.
Tanking teams should not be able to increase quality and not playing for the CL or Cup.
CL and Cup must have teams from the same level.
Remove the top100 list and give rewards for the official competions.
Bring back negotiations and fix this madness with auctions.

In another word, make the game like it was back at 2014 when I started playing and enjoy that much.
