Sivert Mannsverk, a 22-year-old Norwegian midfielder, was transferred to Ajax from Molde FK in September 2023 for around eight million euros. Despite his contract running until mid-2028, Mannsverk has struggled to make an impact in Amsterdam due to injuries and strong competition, playing only a handful of matches for Ajax's first team. He is now part of a group of players who are not allowed to join the first team for the new season's preparations, as reported by De Telegraaf.

Sivert Mannsverk is allowed to leave Ajax. He is currently on loan to Cardiff City and is not expected to return to Ajax.

Sivert Mannsverk was loaned from Ajax to Cardiff City as part of the club's strategy to manage the squad size after Sven Mislintat's tenure.
