在2025年的9月27日，万达大都会球场上，皇马以5-2惨败于马竞，赫伊森作为首发球员在比赛中遭遇了失误。他在防守科克传中的过程中，未能盯好瑟洛特，导致对方轻松进球。这一失误被媒体直言不讳地指出，使得他的防守问题暴露无遗。然而，在这场比赛之前，赫伊森刚刚以6250万欧元从伯恩茅斯转会至皇马，并在赛季初的7场比赛中表现出色，成功跻身西班牙国家队。这样一个20岁的中后卫在加盟后的第一季交出了32场3球2助的佳绩，本应前景光明。

但在德比失球后，他的状态便开始下滑。10月份的比赛中，对塞维利亚的失误导致现场观众的不满，教练组也明确要求他加强专注度。随着比赛的增多，他的状态并未恢复，反而频繁受伤，尤其是在经历高强度的赛季后，赫伊森的连续出场使得身体透支，一次严重的左大腿伤病使他错过了与贝蒂斯的比赛。恢复后，他的状态再也无法恢复到之前的水准。

最终，赫伊森在赛季结束时被评为4.5/10，这一评分不仅反映了个人状态的起伏，也揭示了皇马中场长期缺乏补强的结构性问题。这一系列困境 culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated culminated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilated jubilation 龙8头号玩家

赫伊森在失去国家队名额的情况下，仍表示要重拾自信，克服挫折。2026年4月，他在努力复苏，期望从低谷中重新崛起。
