Anyway, the point is, I'm not sure that just tweaking the stamina system would fix this. Because if you look closely you'll see that pressing is not affected by low stamina. Even when the team are all exhausted, they can still sprint-press until the final whistle... what's affected is stuff like ball control. So as the game goes on and the players get tired (with the team who've played at walking pace just as tired as the team who've sprint-pressed for 90 minutes), the pressure noobs actually find their advantage increased, because the man with the ball being pressed by 4 robots will find it harder and harder to escape the press.
IMO, about Pressure thing.. i'd like to see in the future
1. Left Stick sensitivity
Konami should have at least walking, jogging, running pace both for with/without the ball.
2. Only jockeying modifier button exist
Combine with point 1, you get the freedom in defending.
3. No manual 2nd team mate pressure button
No continuously manual team mate pressure by keeping square button pressed. Instead, you we can use following route :
3.1 By tapping square once, our closer team mate will help pressure, tapping it again will release. or
3.2 By using analoque to highlight 2nd team mate and tap a shoulder button e.g R2 to call for 2nd pressure. tap again to release.
4. No pressure button
You can't just press x and the game will help you to "semiautomatically" go to a dribbler direction.
5. Of course stamina
Proper stamina calculation /system will tell you to think using " 2nd player pressure call "
6. Late movement timing
For example, when an attacker move a bit to the right, your 2nd player will react milisecond late then the attacker. a defending attribute can also put into this to expand a defender individuality. But it should always move late.
Note : in current Off the ball control video, a defender is almost moving at the same time an 2nd controlled player is being moved.

They make him move late by the time a passing/throw in button is pressed. Not that good imo.
7. Player Speed/acceleration/somthing related
Combine it win previous 6 point. Yes, c. ronaldo should run faster than julio cesar. The stamina and dribbling system that will make the balance for it. Not the "rubber band" technology, lol. The current system (PES 2011) for a defender to catch an attacker is quite ignorant short cut method.
Many simple routes could be said/suggested but could be hard in programming/ animation tech ? Since we need almost to complete freedom (nothing to do with complete 360 deg movement). 32 directions would suffice i guess and it is already a lot.
