Hi @Sunstrikuuu
That's not what I'm seeing myself, I've just started an Arsenal save, Raya isn't first choice but Domestic Cup, Zinchenko isn't a star player but an Important Player (note I was able to switch him to Regular Starter on Day One without complaint.) and Trossard isn't a Regular starter but a Squad Player.
Looking at the Arsenal squad as a whole, I would say the starting playing time agreements are all logical (outside of maybe Partey as a Regular starter, but I reckon I could switch him to Squad player after a few months)
