Yeah, they don't cheat, but sure it's hard to tell some times, specially when one's still somewhat new to the game.
Same circumstances, AI striker with poor finishing, dribling, composure, bravery and decision against your high reflexes, one on ones, bravery, handling and position goalkeeper: 85% goals. Your striker with high finishing, dribbling, composure, bravery and decisions against AI goalkeeper with poor reflexes, one on ones, bravery, positioning: 15% goals.
Then if you take out the perception bias it's still a notable advantage for the AI.
If that seems to have decreased to me is because I've been improved since it looked like that with fm05 and my defense is more solid, which leads to less situations of that kind for the AI so that difference is covered by the rarity of it.
Then in this game my team won to ManU, my goalkeeper was the one making all those crazy saves, with helps restore better the trust in the game fairness.
