Some linked to Barca feel Mourinho should be sacked by Real.
But Zubi revealed: "Sandro Rosell later called me and talked with Pep and then Tito. As the president said, sport should have it's own behaviour. We must not lose the capacity to enjoy it. So let's enjoy winning the Super Copa."
On the incident, he added: "I have never seen anything like it in my career.
"It's up to Real Madrid to analyse the situation and make their decisions. If nothing happens, so be it, we move on."
Zubi admitted he was upset with Real's decision not to stay on the pitch and applaud Barca for winning the Copa.
"We were there to clap (in the Copa del Rey) and Florentino (Perez) remained Wednesday in the box but was certainly not amused. There are many faces to the same story."
