JLWE2009CC is similar to PES2008 when it comes to AI. But only 2009 series, 2007, 2008, 2010 not, and I don't know why.
That's why I said that toughness of AI in PES2008 and JLWE2009CC is a fluke, a bug in the game because I think KONAMI didn't wont that.
Pes 2009 to Pes 2014 much weakened AI then Pes 2008. Why? Nobody knows...not even KONAMI itself.
What I found out is that AI respond to certain tactic, and stadium you play on because some turfs slow down ball and some don't.
So choose AI tactic carefully and stadium you play on.
