I have only just bought Pro Evolution for PS2 and the instructions are complete bolox.
It says to do the Onw-Two you need to press F1 and the circle button, then the circle button again just before the ball reaches the player you are doing the one-two with. THIS DOESN'T WORK.

Am i doing something wrong?

Please help Obi-juan your my only hope.

No, you are right, that's an error (one of many) in the manual.
Here you find all correct controls, inclusive the low and high 1-2:
