I trust Neymar but I don't trust his dad and his agent.
Neymar will get his upgraded contract but it's going to be a long several months till the summer if he signs it. Due to his dad handling the the deal you are going to hear so much dumb rumors of "Neymar wants Madrid!" "Real Madrid offering a 40 million contract!" splashed on Marca's Front pages, causing Panic on Barca fanpages,Forums or on Twitter.
Neymar if he really wanted to go to Real he would've done it years ago, when he was actually did join their youth setup for a short time but while his dad wanted him to join on a Permanent basis He wanted to go back to Brazil.
Fast Forward a few years later again Real were also after him along with Several top clubs, and sure enough he again turned Real down despite them offering him more money than us and even his dad and agent again wanted him to go to Real but he wanted to go to Barcelona to play with Messi who he considers an idol of his.
Neymar still has 3 years left on his current deal and made it known he wants to stay here. Neymar Sr is making things so complicated for his son that it's fueling these stupid rumors.
