Hi, nice goal btw BreaL, just to clarify for a few people.
Rooney, Cassano, Henry, Rooney, Del Piero(can do it with both feet) and Pires are the players I'm aware that can do the actual "Special Curling Chip Shot", by running parallel to the goal, with their strongest foot fursthest from the goal, and then shooting with L1+[] - producing the results that BreaL has posted.
Yet many players with good all round shooting stats can curve the ball when shot with R2 held, as the inside of the boot is used to shoot, try Pirlo - good example - doesnt quite have the dramatic swerve and dip of the "Special Curling Chip Shot" but say you are cutting in from the left with pirlo or ronaldinho for example, aim just wide of the far post and shoot with R2 held, it can produce the wonderful result of a shot swinging just inside the far post, milimetres out of reach of the keepers outstrectched fingers.
Hope that helps
