Barcelona are being linked with Manchester City striker Sergio Aguero. El Kun is understood to be a top summer target for Real Madrid president Florentino Perez.

However, Punto Pelota says Barca are also interested in the Argentine and the deal has the approval of Lionel Messi.

Messi gets along well with Aguero, who would arrive as a replacement for David Villa - one player in the Barca locker room not in the Ballon d'Or winner's good books.
