Real Madrid are interested in Racing Club prospect Gonzalo Sosa.

AS says Real Madrid want to sign Sosa this summer and register him with Raul's Castilla squad.

However, they'll face elite competition, with Manchester United, Manchester City and Paris Saint Germain also in contact for the 17 year-old.

In addition, from Spain, Barcelona would also have sent officials to sound out the player's entourage, represented by Martin 'El Ninja' Sendoa.

Sosa is currently seeing senior action at Racing under coach and former Real Madrid star Fernando Gago.
