Some good points there. But they do raise a couple of obvious questions:
One - if England managers pick 'units' from the top three or four clubs because they're used to a system, then why not play that system? When England plays, it's pedestrian and nothing like the PL football that they play week in, week out.
Two - if the players aren't intelligent enough to be able to switch systems, then select more intelligent players. Frankly, I don't think Gerrard or, to a lesser extent, Lampard fit that category.
