I just recently moved to Top Player but only because I found it way too easy to score on Professional. Even then, I always had a hard time keeping the AI from scoring against me. In the ML, I'm always the leader in goals conceded amongst the top 6 teams in the league. The AI just finds its way to score at least once in a game. Mostly, they score on rebounds off the keeper. It's ridiculous that your keeper can't hold on to the ball while the AI keeper always seems to catch your shots.
