The Los Blancos have been heavily linked with the Frenchman, following a revelation from the player himself that he is keen for a new challenge and is open to leaving the Red Devils in the summer.
While United do not want to sell, it is expected that they will want more than the £89million they paid for the player to Juventus and Nadal, who supports the Los Blancos, believes that money involved is sometimes crazy.
"Pogba is a great player. Sometimes the money is crazy, so I don't want something that I believe is exaggerated in terms of money. That's all," he said as quoted by Express.
The Frenchman who is currently with the Red Devils during their pre-season training in Perth is expected to stay by manager, Ole Gunnar Solskjaer who recently made it clear that he wants to keep hold of the midfielder and will not want to let him go in the summer.
It will be interesting to see how this transfer situation pans out considering that the Los Blancos have already spent huge swathes of money so far and might not have enough money to launch a bid for him.
