I'm sure the media is just overblowing the situation. They heard nothing so far, so they decided to fabricate the issues.
I remember reading an article about VV's and Xavi's contract renewal over a summer. Man, the media was going nutz, saying they're going to all these other clubs, etc. Then the preseason came around, they signed a new contract, and said to the media, something like, "over the summer it hurt to read all these fake stories on how i was leaving and contract negotiations were breaking down." etc etc. not an exact quote, but the jest of what he/they said.
Anyway, I wouldn't worry about Busquets.
