"Real presented themselves as a team in the second leg, Paris did not", former France global Sagnol told Kicker.
Zidane has begun treating domestic games nearly like trials for Europe, rotating key players or trying other ones in unfamiliar positions.
Gareth Bale came on as a second-half substitute with speculation surrounding his Real future and Zidane insisted he remains part of his plans.
Zidane became the world's costliest player in 2011 when joining Madrid from Juventus for £48m.
After Real's team display last Tuesday, they may face an uphill struggle, not least Bale with Zidane no longer married to a 4-3-3 formation and Vazquez boasting 13 assists this season.
"This year we belong there to be honest, it should not be a big surprise and the next round will be very hard".
"I'm not going to talk about a player that is not mine".
PSG President Nasser Al-Khelaifi has made no secret of his desire for PSG to one day - and sooner rather than later - reign on the continent and lift the Champions League, Europe's leading club competition.
I do not, for one moment, think that Neymar's injury was the main reason PSG did not get past Real Madrid. I felt we needed to keep pressing and playing offensively. With Ronaldo coming into his best form and players such as Asensio and Vazquez showing the depth of their squad, you would have to be fearless to bet against them.
They let coach Carlo Ancelotti go to Real Madrid after stalling over his demands for a new contract and then unceremoniously dumped Laurent Blanc his replacement in the summer of 2016 to make way for Emery. He has constantly praised the industrious winger in the media prior to the second leg and started him in five games on the spin before resting him against Getafe last weekend to be ready for 90 minutes of tearing up and down the right-hand side in search of opportunities on Tuesday. It's Lionel Messi and Cristiano Ronaldo - and it's not the least bit surprising that they are stepping up at just the right time for their teams.
Only last season did Real Madrid manage the domestic and European double as Luis Enrique's Barca imploded in Spain and they breezed past Juventus in the Champions League final. "He is a good player but he doesn't play for us, I'd rather speak about my own players".
