I don't believe you can judge - for example both Rooney and Lampard played very well for thier respective clubs but are awful in the World Cup. I accept that they can be flattered by good team-mates, but not to the extent these players are. Add in Gerard and Terry and you are talking about tranfer targets for every side in Europe.
Until they introduce salary caps, television match officials and give the refs microphones soccer will continue to decline in quality IMO.
Though we are not now that strength which in old days moved earth and heaven; that which we are, we are; one equal temper of heroic hearts, made weak by time and fate, but strong in will to strive, to seek, to find, and not to yield.
