The clearest signal so far is Zubimendi’s stated intention: he is not considering a winter exit. The reported Atlético interest remains a separate matter, and a link alone is not evidence of a concrete offer or active negotiations.
That distinction matters in a January window, when speculation can quickly be treated as a developing deal. For now, there is no confirmed move to assess. Any change would depend on developments beyond the player’s denial, including whether interest becomes formal and how Arsenal respond.
Zubimendi’s role as a composed, technically assured midfielder gives Arsenal a reason to value stability. Players who can help control possession and connect defence with attack are difficult to replace midway through a season, particularly when a club is balancing domestic and European commitments.
His denial also takes some pressure off the immediate conversation around Arsenal’s midfield. Rather than preparing for a departure, the focus can remain on how he fits into the team’s plans. That could change if the reports develop, but there is no basis yet to treat an exit as settled.
The story to watch is whether Atlético’s reported interest produces a formal step before January closes. Unless that happens, Zubimendi’s message is straightforward: he is not planning to leave Arsenal this winter.
