I need your help!

So i'll set the scene.


Me and my mate are super competetive.

We started a multiplayer save where I was City and he was United. He got sacked in his second year so he joined Everton. He made us unsackable so he couldn't get sacked again. He was mediocre at best with them for season after season after season and never won anything while I was winning everything, it's safe to say he was burning inside. All of a sudden my good players start turning shite, like from 4 stars to 2 stars people like Aguero and James Rodriguez turned to peasants who couldn't kick a ball. Conveniently at the same time he buys Moussa Dembele (the young one) and some regen named Oliajevtsky or some shit. Anyway they both have literaly kicked around 150 goals between them in 2 calendar years. His team start turning amazing with all these players who seem to have come from nowhere.

I think I busted him using the editor once but i knida ignored it and thought nothing of it. However it's bugging me severly now because he is all smug he is winning. Is there anyway I can prove he is cheating and editing his players and mine? Can I reset the editing to default somehow? Is there anything I can do, please help. For the sake of football manager help me.

Only the host of the network game can use the editor, as far as I'm aware. As for reseting it to default; it is impossible once the changes have been saved. As for catching him using the editor; just note if your players' attributes have literally hit the floor all of a sudden. Also, here is a screenshot of a pretty much fully-developed Moussa Dembelé (who is a beast in FM anyway), so if his Dembelé's attributes are ridiculously higher than this one's, they've been edited.

His is so much better, i'll post a photo later tonight. He will just deny deny deny unless I have solid proof. He will put down his players brilliance to his managing or some bullshit like that.
I need to catch this guy somehow.

P.s What skin is that, it's amazing.
