Former France international Zinedine Zidane has said that it will be bad for Real Madrid if Messi is fit for the upcoming El Clasico.
Los Blancos play the Catalonia club at the Santiago Bernabéu this weekend for the first El Clasico of the 2015-16 season.
"Everyone wants to see Messi on the pitch, all the time," Zidane told Sport Bild. "But from Real's point of view I will certainly not say that it'd be good were Messi to take the field."
Asked if Barcelona needs Messi, the Madrid legend said: "Do Barcelona need him? Sorry, we are talking about Messi here. Every team in the world would be delighted to have someone like him on board."
He also said that German midfielder Toni Kroos has changed his game since his move to Real Madrid from Bayern Munich.
"He has changed his game since he got here," Zidane explained. "We knew that he's used to German football, and that the Spanish game is way different, and is also about beauty, especially here at Real. But he immediately adapted [to] this style."
