Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
If you're going to accept the abbreviations for wing attack (WA), wing defence (WD), centre (C), goal keeper (GK), and goal defence (GD), you might as well accept the abbreviations for goal attack (GA) and goal shooter (GS). Also, I think you should allow goal shoot for goal shooter and goal keep for goal keeper, because those are equally acceptable terms for those positions.
