I think, and I could also be wrong, that you are playing with top player boosts and the AI are playing with Superstar boosts which should make the game harder for you. As I said though, I could be completely wrong
I'm the same but with pc pes 21 modded. EA and Konami are both the same as stock pes 21 is a bit shite too. Both games need heavy modding to be enjoyable on single playerAfter going back to the PC I can't play it on the console again. It just shows you how lazy and greedy EA are.
