this is based on my FM 20 experience.
1. players has run how much(distance) last matches should be included in player stats window, so we can properly manage game time and reduce injuries
2. add player stat window: ball recoveries, clearances and lost possession in the game. these stats are in the modern game now along with XG
3. improve rating for more defensive minded players, not just based on goals and assist or key passes/chance created
example: ndidi, kante, fofana
4. add new staff, performance coach to help boost player determination/concentration in match preparat
