Norwegian Centre-Back Kristoffer Ajer, 27 years old, has signed a contract until 2030 with an option for an additional season. Keith Andrews expressed happiness that Kris agreed to a new deal. Ajer stated he is very happy to extend his stay and described Brentford as being probably the best club in the world from Monday to Friday. The Norway international, who has 48 caps and 2 goals for his country, joined Brentford from Celtic in July 2021 for a fee of €15.7 million. This season, he has made 16 appearances and provided 1 assist in the Premier League. His current market value is estimated by Transfermarkt to be €16.00m. Before the extension, he had been linked with clubs including VfL Wolfsburg and Beşiktaş; reports from late 2025 indicated that Wolfsburg had a €15 million offer for the defender rejected.
