Zidane was in Paris at the same time as the Emir of Qatar for last month’s Champions League final at the Stade de France, which was won by Real.
Earlier, PSG announced the arrival of Luis Campos as their football advisor to replace the departed Leonardo.
The 57-year-old Portuguese helped Monaco to the French crown in 2017 as well as Lille four years later and worked alongside Kylian Mbappe on the Mediterranean coast.
One of Campos’ tasks will be player signings with RMC Sport reporting free agent Paul Pogba is waiting for the official arrival of Zidane at PSG to start discussions about joining the side.
“I am delighted to be joining Paris Saint-Germain, which I consider is the most ambitious and exciting club in world football,” Campos said in a PSG statement.
“I believe strongly in and share the vision of the club and I cannot wait to get started to further unleash the great potential of this exceptional club.”
The new French top-flight season begins on August 6 with the French Trophée des Champions five days earlier as PSG face Nantes in Israel.
