United are bigger worldwide than Madrid and Barca. The international audience couldn't care less who a club is owned by.
I don't think so, there is no way to know for sure unless somebody counts them all, but in the reports I have seen Barca comes out on top miles clear of any other club.

And in terms of attractiveness Man Utd don't come close, I can't think of when a truly elite player at the top of his game joined them they always chose Barca or Real because they are the biggest clubs.
