The race for the highly-rated River Plate talent is officially over, with the Spanish giants emerging victorious.
While Mastantuono’s release clause is set at $45 million, Madrid and River are in the final stages of negotiating a different structure to the deal. The Argentine club has already been informed of the player’s decision.
The"deal" is expected soon as Los Blancos continue their policy of snapping up top young talents from South America.
