Mats Knoester was born on 19 November 1998 and hails from the Netherlands. A formidable defender, Knoester primarily stands as a central figure in Aberdeen's defence. Standing 6ft 1in tall (1.86m) and tipping the scales at 12st 1lb (77kg), he wears the number 5 jersey for his club.
As of today, the market values him at approximately £510k according to data available on Transfermarkt. His contract with Aberdeen remains valid with a running period of 2 years and 1 month, bringing it to an end on 31 May 2027.
Starting his professional career in July 2014, Knoester joined Feyenoord—part of Eredivisie, the top-tier Dutch league—as a trainee. He then completed a transfer to Heracles Almelo, another Eredivisie team, in January 2019 for an undisclosed fee. Across several seasons with Heracles, Knoester impressed with regular league appearances, even finding the back of the net twice in the 2020/21 season.
July 2022 witnessed his move from Netherlands to Hungary as he signed with Ferencvaros in the Nemzeti Bajnokság I league. After a solid season with 27 league appearances, his participation dwindled to only two league games in the 2023/24 season. In September 2023, Knoester migrated to Denmark's Superliga on loan to AGF Aarhus, where he contributed to 14 league games.
Upon the completion of his loan in July 2024, Knoester returned to Ferencvaros and once again made his mark with 27 league appearances. However, in January 2025, Scotland beckoned as he transferred to Aberdeen in the Premiership. Currently, in the 2024/25 season, Knoester has featured in ten league matches and three Scottish Cup matches, signalling a promising start to his time at Aberdeen.
