The only way the CPU can keep up this type of pressure is by sprinting. The fact that stamina has no effect whatsoever on players is laughable really, and until that's sorted there is nothing they can do to properly try and recreate the game. Sport is dominated by fitness and the limits of what the body is capable of, so when I see a team manfully pressing, sprinting non stop, cramming men at the back then sprinting out on the break as the CPU does in PES, I'd expect that tactic will weaken those players the further the match goes on because no team can match those stamina and energy levels. The way the CPU plays, then from 65-70 minutes onwards, they should be slower, passing more erratic, make marking and positioning worse, because they should be physically shattered. On the other hand, if I've been making the ball do the work and keeping possession then I should be more fresh, quicker and have more concentration than the CPU. It needs to have some kind of consequence for expending the energy it does by keeping things tight at the back, but it doesn't. In fact, somehow the game does the opposite and makes the CPU more physically aggressive, faster, with more pinpoint passing the longer the game goes on.
After all, coaches always tell players learning the trade to "let the ball do the work", and there's a very good reason for that. Konami seem to completely ignore it though.
