As a loyal PES fan theis game is a massive let down.
In master league mode you are now forced to suffer an irritating chap who stands by a board and tells you the same thing before and after each game. You are also forced to listen to players moan after each game because they havent been selected, were played out of position, want a different squad number etc. The above do not add anything to the game, they are just annoying.
In terms of gameplay, as other reviews have said goalkeepers are useless, they regularly dive past 40 yard free kicks and let daisy cutters trickle in. Defending is also too tough as free kicks are given for nothing. Also very difficult to run away from players once you've beaten them.
Avoid this one, the 2011 version is better.
