I think there are certain things you can do that help, like measuring your run up properly and really practicing it so that you've got plenty of momentum and your landing foot is in the right place every time. Denmark seemed just to randomly run up. It's a simple technical test but under obvious pressure, though those keepers were huge compared to someone like De Gea who is tall but relatively skinny. One of the pens just passed over his hip from what i remember whereas the two last night would have stopped it.
