debateable Not really.
It is, the dominance of the top two doesn´t wrest merit from the others. Not at all. Top to bottom, I´d take La Liga.
Iniesta maybe, but Xavi is well into the down side of his career.
As is, was, Lampard. Xavi´s role is less physically taxing, and geared to assisting, he´ll further strengthen the aforementioned average.
As I said before, apples and oranges.
Very different players, in different systems, and whose roles are different. Always have been, hence my quick retort to all your superiority claims of Lampard. They are called upon to do different things, and all do them very, very well.
