The French legend bowed out after guiding Los Blancos to a third successive Champions League trophy.
“I’ve got my feet up and am feeling good,” Zidane told AFP at the inauguration of a playground in Paris.
“I don’t know what I’m going to do,” he added. “The most important thing is the decision I’ve taken, the rest we’ll see.”
The 45-year-old is pleased that he managed to step down during a period of success and insists it was the right time for a change.
Zidane also revealed that he was no longer confident of maintaining the standard and frequency of success he achieved.
The former French international also confirmed that no other job in football influenced his decision to quit.
Madrid are yet to appoint Zidane’s successor with several high-profile names in the mix.
Real Madrid-bound star Vinicius Junior was in floods of tears on Sunday night after playing his last match for boyhood side Flamengo in the Brasileirao Series A league at the Maracana Stadium.
The 17-year-old, who officially completes his move to Los Blancos next month in a deal which has been in place since May 2017, will link-up with his new Whites team-mates during their pre-season tour of the United States.
However, despite earning a move to arguably the biggest club in the world, the Brazilian forward leaves the club where he started his career as a child with a heavy heart.
Watch the video below to see how emotional the talent was as he appeared in front of his home fans for the final time as Flamengo downed Parana 2-0.
The Daily Star understands United are interested in luring Bale to Old Trafford and their hopes were raised when he admitted he would consider leaving the Bernabeu after he guided Los Blancos to a third successive Champions League success.
Bale hinted at a move away from Madrid after his match-winning display in the 3-1 win against Liverpool in Kiev.
“I feel like I deserved to start because I’ve been playing very well,” he said.
“For me personally, I feel I should be playing week-in and week-out and I haven’t been.
“I haven’t been playing as much as I would like and I’m going to have to sit down with everybody at a big table in the summer and seriously consider what move I’m going to make next.”
Reports in Spain suggest the Red Devils face competition from Bale’s former club Tottenham, who fancy bringing the Wales international back to White Hart Lane five years after selling him to Real.
Bale reportedly favours a return to Tottenham instead of joining Jose Mourinho’s team, but Old Trafford bosses are willing to spend more on Bale than Spurs.
Bale found himself out of favour for most of the season under former boss Zinedine Zidane. Despite his limited action, Bale still struck 21 goals in 39 appearances.
He added: “I feel like there’s still a lot more to give for me and that’s why I need to be playing week-in and week-out, that’s what I need.”
