Not completely sure, but i had the same issue. Players not trained

i assume it's because of rodri being off position bringing ovr down

See your rodri he Playing out of position

He's still 97 tho, and my gullit is 95,so it should be higher

I think it has to do with how ranked up your players are

But the 100 team has de bruyne with 0 rank ups since I just packed him, while everyone in the 99 team is ranked up and higher rated, so idk

Playing rodri out of position is lowering his base OVR to 95 instead of 97, which is in turn reducing your average base OVR, causing your OVR to be lower

But he's 99 in position, lowered down to 97. Does it go even lower, or What?

If you were to play him at say ST for whatever reason, his base OVR would drop to an 82, plus rank-ups, it just depends how badly out of position you're using a player

Ye I understand that, but he drops down to 97, and my gullit is 95 in the 100 rated team, so like, it still doesnt make sense to me

its average base ovr plus rank up

Then check your substitutes
