Today I read an interview in a german sports magazine with Neymar (from the 18th of July). He said there is no pre-deal, neither with Barca nor with Real. He said he wants to stay in Brazil until 2014, as he´s happy to play for Santos and doesn´t want to rush the move to Europe. He seemed like a smart kid, the interviewer also pointed out how friendly and down-to-earth Neymar was during the interview.
I don´t think there´s anything happening, both Barca and Neymar know that a move this year would be too soon and he´s not really needed. Not as much as we need a CB/DM, that´s for sure.
