Marcelo's move to Juventus is being blocked by Perez

Calcio Mercato reports that Florentino Perez is prepared to declare that veteran left-back Marcelo is not for sale in January with Juventus being heavily linked with the player. Marcelo and Cristiano Ronaldo are close friends and the duo reportedly wants to join arms once again in Italy.
However, Florentino Perez is against the idea and Real Madrid not hiring Antonio Conte could have further complicated the situation for the Brazilian who reportedly wants to follow Ronaldo to Turin.
The report states that Alex Sandro could have been motivated to join Real Madrid in a deal which would see Marcelo going the other way if Conte had taken charge of Los Blancos.
However, in the absence of Conte, Real Madrid have no replacements lined up in case Marcelo departs.
