What's up with one-two's??


Youth Team
After playing Pes5 and finishing couple of seasons in ML I've come to conclusions that ''give and go'' combination doesn't work like it used to do. I understand that due to the more physical approach players are sometimes bumping into each other thus ruining one-two situation, but that's not the case.
Almost 50% of the time when I hold L1 and pass to a teammate the passer does not even start the run. At start I thought this was gamepad issue, but now I realize it's not. Other type of occasion with one-twos are like that - after making a pass player bursts forward a few meter (3-6) and then stops. Why? Is it another way of making game challanging? By disallowing the one-twos 3/4 of time?
What's your experience with this?
