The Spaniard admits he is not sure where he will be plying his trade next season, with talks over his situation at Santiago Bernabeu due next month
The 22-year-old moved to the Spanish capital from Real Betis in 2017 for €17 million (£15m/$19m) and he has since racked up 56 appearances for the Blancos across all competitions.
During the 2018-19 campaign, he featured 34 times, starting on 19 occasions, but Madrid endured a nightmare season which ended in abject failure.
Ten months after leaving his managerial post covered in glory following a third successive Champions League win, Zinedine Zidane returned to the club to steady the ship and he has already begun to implement a number of changes.
Ceballos is thought to be one of several first-team stars deemed surplus to requirements by the Frenchman and he has been linked with a summer move to Tottenham in recent weeks.
The ex-Betis playmaker is currently away on international duty with Spain‘s U-21 squad ahead of their European Championship campaign, which kicks off on June 16.
Ahead of the tournament, Ceballos has conceded he could leave Madrid during the current transfer window.
“I started well under [former Real Madrid coach Julen] Lopetegui, but once he was fired, I, unfortunately, became secondary,” he told Onda Cero Radio.
“I’m not going to say what was said regarding my talk with Zidane but what I can say is that he was clear with me and once the Euro U21 is over, I will decide my future.
“My aim is to play wherever I go and prove that I can compete in any team in Europe. I hope to succeed because nothing is going to defeat me.”
Zidane has been very busy in the market, having already managed to lure Eden Hazard, Luka Jovic, Eder Militao and Rodrygo to the Bernabeu.

Lyon left-back Ferland Mendy is also expected to complete a move to Madrid in the coming days and the French boss is prepared to target Manchester United’s Paul Pogba thereafter.
Ceballos is unlikely to see regular football for the Blancos next year and so his career development might be better served elsewhere.
It remains to be seen whether or not Tottenham will launch a formal bid, but the Premier League outfit are expected to be active in the window after not signing any new players for over a year.
