There is still time for now especially with the current situation for Madrid they can still delay even though the winter transfer is in sight but they can still hold back if they still don't find a suitable candidate for a pure striker but this should not be allowed to drag on because after all their deadline for finding candidates is until the end of this season.
There is still quite a long time left and I think for now in this January transfer window they will still prioritize about the defense rather than for strikers. Because after all, by looking at the current situation, their defense still looks weak with several players who have fitness problems such as Militao who must be out for a long time and Rudiger and Alaba who are still very vulnerable to injury.
Madrid must consider this because if this continues to be allowed to recruit then I think this could disrupt their stability. As for the current striker problem, even though this is also a little bit important, but until now their attacking line is still quite good even if they try to bring in a pure striker now, it's actually not a problem, it's just that it's rare to transfer star players in January because they always rely on the end of the season to sign bigger players (star players).
