Real Madrid have declared midfielder Fede Valverde almost unsellable with a staggering £448million release clause after interest from Manchester United.
The Uruguayan is enjoying a stellar season under Zinedine Zidane for Los Blancos and has already attracted interest from all over Europe.
Ole Gunnar Solskjaer has identified Valverde as a key target this summer but has suffered a major setback in his pursuit given the 21-year-old's huge release clause.
According to Sport, United are aware that Madrid are not willing to budge at all and the transfer will be impossible.
