A Barcelona delegation will fly to Brazil this week for talks with Santos star Neymar.

Punto Pelota says renewed interest from Real Madrid and Chelsea has Barca officials nervous and they want a commitment from Neymar when they meet this Thursday.

Barca are pushing Neymar to come to Europe this summer and want a deal in place before July 1.

The Spanish champs are well aware of the frenzied behind-the-scenes action from Real president Florentino Perez and Chelsea's revived interest. The developments have forced their hand this week.
