I don't understand what point you're making? You've said to me the same thing I've said to you. I don't know whether you're agreeing with me or trying to put up a counter argument.
I'm agreeing in part. But my initial point was that when English football was supposedly cursed by a lack of intelligence, English clubs (with British players/managers/coaches) dominated Europe for a decade. That's just a fact. Since becoming more intelligent (apparently) we've done quite badly in Europe, relative to that period. I don't really have anything else to add.
