flip flap? try this someone on a diffrent forum has suggested this
--Choose Ronaldinho and run to the right (dont sprint, just hold right)
--Press Square then X + down (to perform the fake shot - You see when ronaldinho does the fake shot he makes the ball chip upwards a bit)
--As soon as you've done it and the ball is in the air press R2 + Up (This will move up doing the shimmy and kind of look as if hes moved the ball whilst its in the air)
--After doing the shimmy, let go of R2 and Up and just hold right so that he continues running to the right instead of moving off to the top right.
cant say i tried it as my ps2 has been packed away
