Kristoffer Ajer

In January 2026, Transfermarkt reportedly estimated his market value at €16 million. Reports from late 2025 stated that a €15 million offer from VfL Wolfsburg was rejected by Brentford during the summer of 2025. Around that time, in August 2025, his market value was estimated by Transfermarkt to be €18 million. His last completed transfer was from Celtic to Brentford in July 2021 for a fee of €15.7 million.

Our valuation for Kristoffer Ajer is primarily driven by the rejected €15 million offer from VfL Wolfsburg in summer 2025, which sets a clear floor. His subsequent contract extension with Brentford until 2030 significantly strengthens the club's negotiating position. The valuation is further supported by market value estimates from Transfermarkt ranging from €16 million to €18 million, aligning with the fee Brentford paid in 2021.
