Thank you, there is few others like Shorty_alien who you should really talk to since he like me played the other game on manual last year, both got fed up with the game because the 400+ matches played there was just no depth!
I know PES 2010 would not be a classic and the animations were not up to scratch but EVER from Gamescom last year i could see the AI was something special even. Teams behaved and played like teams. The defense kept it's line and defensive midfielders actually do their job!
There was a almost freaky goal i scored with Pazzini in my manager. The off the ball movement.

Pazzini was running offside along the back four to annoy them and lose his marker, I managed to pick him out in space where he was able to score. I have 3 other strikers who never made runs like that, Cassano who drops off 24/7, Stevanu who just plain average and another average striker who could never work the space Pazzini could.
Players like Inzaghi, wow this game does poachers justice! look at this hat trick he scored vs Harmmby. from 1:03 to 1:32

His off the ball movement is to always drift way from defenders and look to get into spaces. I love the 3rd goal, the first touch, he had the awareness that there way space behind for him to dummy and shot on his strong foot rather than take a basic touch. Their whole game is about scoring.
Yet on the halfway line he's funking useless just like in real life
This even more apparent with Strikers like Soren Larsen. No pace, dribbling skills or technique whatsoever but a giant int he box, holds up very well and scored goals for my Villarreal team (cheap buy aswell

)
I actually enjoy playing 4-5-1 with good/average teams like Japan, Bordeaux, etc.. It's actually fun stifling big teams with them and look for the odd mistake and grinding out a 1-0 result!
Thats what made PES 2010 a good game for me despite the dreadful animations! Obviously it's not better than average since the animations were not up to scratch and things like dribbling and flair, trick were pretty terrible. I'm a person who loves that type of stuff
