Several of Europe's elite clubs are said to be chasing De Ligt, with Ronaldo encouraging the 19-year-old to join Juventus while former team-mate De Jong talked up a move to Barcelona.
But De Ligt has not yet made his decision and plans to take his time, telling Mundo Deportivo: "I still do not know what my heart says, I have been concentrated all the time on Ajax and the national team.
"Now, on my holidays, I will be able to think about it and decide what I am going to do with my future.
"For me, the most important thing is to know that in the team where I go I can have prominence and play many games. I do not know when I'll have it resolved, but I'm going to take my time."
Discussing the pitches from Ronaldo and De Jong, De Ligt continued: "Of course it would be nice [to be reunited with De Jong], but I must also look at what is best for me.
"I do not pay attention to anyone, I have to choose my own path."
Responding to suggestions Barca might not be able to match financial deals elsewhere, he added: "Money is not the problem.
"Maybe it's not the time yet. It's something I have to think about and decide during my holidays - nothing more."
