I never said that they are, and I'm as unbiased and objective as far as Juventus fans go; I sometimes even berate our own players FFS.
My point of contention is not whether they are superior or not.
You are saying they are lightyears ahead; I'm merely stating that they are better, but not by such a substantial margin. So, let's say you rate Barca's midfield as 9 or 9.5 (to which I would agree), I'd give Juve's a 7.5 or 8. Pirlo has been magnificent, and obviously he provides a lot of balance. A lot is riding on how he performs next season as well.
I wouldn't swap any of our midfielders for Barca's, not because they are better, but because the way our midfield functions/performs as a unit, and I intend to keep it that way
