FIFA 11 Hints for PC
This only really applies to players with the Long Shot or Distance Shooter speciality, or players with a high statistic in Long Shots. However, it can work for most players.
It is difficult to score long shots from outside the penalty box with a regular shot. You might find it easier to do so with a finesse/placed shot. From a long distance, these shots are surprisingly powerful (if timed correctly) and are more likely to end up in the back of the net.
The reason for this is that there is far less curl in the shot from a finesse shot, so that it does not result in the ball curling out wide or towards the goalkeeper.
