I just personally find this kinda useless :P it doesn't even show the reality, because every goal counts, no matter where you are from. And when you have backline/cdms full of englishmen, it's unlikely they'll score. And you won't appreciate them then, unless they score a header from corner.
Ok this is not to bash any team so my folk just relax.
An interesting data from BBC this year shows a again the point of view that big teams are not "English" teams. Since English national football has hit rock bottom despite the noises they have been making in all big tournament... Should we appreciate Arsenal and Wenger a bit more?
