Van de Beek confirmed during the transfer window that Madrid contacted Ajax over a possible deal, but a move to the LaLiga giants did not materialise.
The 22-year-old continues to be linked with Madrid as he stars for Eredivisie holders Ajax, however, the Netherlands international wants to see out 2019-2020 in Amsterdam.
"I don't want to leave during the winter break," Van de Beek said.
"I play here all season, I finish at Ajax this year. That gives me clarity and tranquillity. I will see what happens next.
"Maybe someday in my career it will happen that I switch club during the winter break, but now I don't like it."
Van de Beek scored as Ajax accounted for Valencia 3-0 in the UEFA Champions League onThursday (AEST).
He has netted three goals in all competitions this term, while supplying four assists in Eredivisie.
