The Juventus midfielder is hot property in Europe, with his former English employers understood to be the hot favourites for his prized signature, with a €120million fee allegedly already agreed with the Old Lady.
Reports in Italy however suggest that a disparity regarding monies owed to his super-agent Mino Raiola have delayed the deal, with a further spanner now thrown in the works as Los Blancos head coach told media that his La Liga club are also interested in bringing the 23-year-old to the Santiago Bernabeu.
"In this moment we are still working [on a move for Pogba], and I cannot say anything more," Zidane said.
"Until August 31 anything can happen, but today he is not a Real Madrid player and I cannot talk about what will happen.
"I always say how things are, but now is not the time to talk about this. A lot of clubs are interested in Pogba.
"Real Madrid always want the best players. But we owe Juventus respect, and I can't say anything more out of respect."
Pogba scored 10 goals and provided 16 assists in 49 games as Juve claimed the domestic double last season.
